Abstract
Purpose
The game strategies differ when different regions participate in the oil game. Under what circumstances will different participants choose cooperation or sanction strategies? This is the core issue of this paper.
Design/methodology/approach
Regarding the current and future game behavior between different regions in the oil trade, this paper constructs an evolutionary game model between two regions to explore the possibility of sanctions strategies between the two sides in different situations.
Findings
The research finds: (1) When the benefits of in-depth cooperation between the two regions are greater, both sides tend to adopt cooperative strategies. (2) When the trade conflict losses between the two regions are smaller, both sides adopt sanctions strategies. (3) When a strong region trades with a weak region, if the former adopts a sanctions strategy, the net profits are greater than the benefits of in-depth cooperation between the two regions. If the latter adopts a sanctions strategy, the net profits are less than the trade conflict losses between the two regions. There will be the strong region adopting a sanctions strategy and the weak region adopting a non-sanctions strategy. At this time, the latter should reasonably balance the immediate and future interests and give up some current interests in exchange for in-depth cooperation between the two regions. Otherwise, it will fall into the situation of unilateral sanctions by the strong against the weak.
Originality/value
There is no paper in the existing literature that uses the evolutionary game method to analyze the oil game problem between the two regions. This paper constructs a two-party evolutionary game model composed of crude oil importers and crude oil exporters and, based on this, analyzes the evolutionary stability between the two regions under sanctions and cooperation strategies, which enriches the energy research field.

1. Introduction
With the rapid development of the global economy, the demand for energy in various regions has risen steeply. Energy supply is related to the socio-economic development and energy security of a region (Nyga-Lukaszewska and Napiórkowski, 2022), which has attracted widespread attention around the world [1]. Traditional fossil fuels are still a key component of various energy sources. According to the Statistical Review of World Energy 2023, traditional fossil fuels such as coal, natural gas, and oil account for up to 82% of total energy consumption. Furthermore, the demand for and production of oil has increased significantly and is still rising. For example, in 2022, global oil production increased by 3.80 million barrels per day, and Saudi Arabia alone had a daily production increase of 1.182 million barrels [2]. Oil plays a critical role as a strategic scarce resource. Oil resources are still indispensable for economic recovery in all world regions (Yu et al., 2023), but the rapid consumption of oil resources and the increasing participation of more and more regions in the international oil trade markets have made the relationship between oil resources in global trade increasingly complex (Ji et al., 2014). Therefore, oil and oil products will remain the focus of the development game between regions.
Issues of benefit distribution and energy security always accompany the oil game between different regions [3]. Therefore, different regions will adopt cooperation or sanctions to participate in the game (An et al., 2014). For example, in February 2022, China and Russia signed an oil cooperation agreement to guarantee the supply of crude oil to refineries in western China [4]. In July 2022, Russia and Saudi Arabia plan to jointly maintain the oil cooperation concept of “OPEC +” (OPEC and non-OPEC participants) and avoid unnecessary losses caused by malicious competition [5]. Different regions also often defend their interests through sanctions or confrontation. For example, oil-exporting countries such as the United States and OPEC countries compete for market share in oil exports, ultimately ending with OPEC countries boycotting large-scale crude oil exports from the United States and reducing competition intensity through production cuts (Zhou et al., 2022). The European Union countries and Russia have adopted a sanctions strategy against each other. Specifically, the European Union countries prohibit the import of Russian crude oil and oil products by sea, and Russia stops sending natural gas and oil energy to European Union countries [6]. So, the game strategies differ when different regions participate in the oil game. Under what circumstances will different participants choose cooperation or sanctions strategies? This is the core issue of this paper.
Therefore, this paper examines interregional oil gaming through the construction of a two-party evolutionary game, and explores the impact of the key factors, i.e. the benefits of in-depth cooperation, the trade conflict losses, and the net profits obtained from sanctions strategies, on the trend change of the evolutionary results. Compared to the net profits obtained from both regions adopting sanctions strategies, if the benefits of in-depth cooperation are greater, both regions are inclined to choose cooperation strategies. Furthermore, lower levels of trade conflict losses between the two regions would increase the likelihood of adopting sanctions strategies. When one region’s net profits from adopting a sanctions strategy exceed the benefits of in-depth cooperation, while the other region’s net profits are lower than the trade conflict losses between the two regions, a scenario of unilateral sanctions may evolve. The above illustrates that, for policymakers, paying more attention to the long-term interests of the regions and potential losses from trade conflicts is advantageous for strategic choices and adjustments at the regional level.
There are three contributions to this paper. Specifically, (1) There is no paper in the existing literature that uses the evolutionary game method to analyze the oil game problem between the two regions. This paper constructs a two-party evolutionary game model composed of crude oil importers and crude oil exporters and, based on this, analyzes the evolutionary stability between the two regions under sanctions and cooperation strategies, which enriches the energy research field. (2) Based on the complexity of the oil game problem, this paper investigates the key factors influencing the choice of sanctions and cooperation strategies in oil games between two regions, and clarifies the boundaries of different strategy choices between the two regions. This enriches the research on oil games between regions. (3) This paper constructs an evolutionary model of oil games between two regions, and theoretically depicts the possible evolutionary paths of oil games between the two regions. This can provide a basis for practical decision-making on oil issues between regions.
The rest of this paper is structured as follows: The second section reviews the relevant literature on oil games between regions. The third section establishes a game model and analyzes the evolutionary states in various situations. The fourth section conducts a numerical simulation analysis. The fifth section gives the research conclusion and puts forward the management implications.
2. The oil game between regions
The oil game has always been the center and focus of the energy game, and the game between different regions around oil is also the focus of this paper. Many scholars have studied the oil game between regions from the perspective of cooperation and confrontation between different regions.
From the perspective of cooperation between oil exporting regions, for example, Berk and Çam (2020) studied how cooperation agreements between the Organization of the Petroleum Exporting Countries and non-OPEC producers affect the structure of the crude oil market. They constructed a crude oil market equilibrium model with a spatial structure to predict future oil export production. Moreover, they believed that the cooperation of oil exporters would revolutionize the oil market. Mohammad (2021) studied the resource sharing and economic similarities among the GCC (Gulf Cooperation Council) countries within the regions, and concluded that although regional environmental cooperation among GCC countries is not comprehensive, it has high value for interregional environmental cooperation and policy coordination.
From the perspective of cooperation between oil-importing regions, Zhang et al. (2018) analyzed the possibility of China and India cooperating on oil tariffs in the face of the threat of oil supply disruptions from a game theory perspective. They concluded that cooperation can bring higher benefits and greater resistance to the threat of oil supply disruptions. Therefore, they called on China and India to adopt more cooperative strategies in the oil game. Chang et al. (2023)argued that cooperation among oil-importing countries is beneficial for managing the asymmetric impact of oil price volatility on their CAB and contributing to economic stability.
From the perspective of trade cooperation between oil regions, Wei et al. (2022) analyzed the impact of new trade relations on the efficiency of international oil trade networks under different trade cooperation strategies. Liu et al. (2020) used the complex network method to analyze the complexity and dynamics of oil import and export between regions from the perspective of oil security evaluation, and the results show that the global oil trade shows a pattern of diversified import sources and strengthened regional cooperation. An et al. (2020) analyzed the characteristics of South Korea’s oil import projects. They believed that South Korea should actively establish a level of oil import and export cooperation with North Korea and Russia, actively explore opportunities for oil cooperation, and carry out diversified oil cooperation strategies. Chen et al. (2021) used the logarithmic mean division index (LMDI) method to study the competitiveness and complementarity of BRICS countries in oil trade and to reveal the import and export advantages of different countries. The results showed that India and Russia have high complementarity in crude oil trade, but the driving factors are unstable. China-Russia trade is stable, but further cooperation is still needed. Zhao et al. (2021) used the improved-entropy TOPSIS method to study the oil cooperation between China and countries on the “Belt and Road Initiative,” evaluating the risk level of cooperation between China and different countries based on multiple risk indicators, providing a reference for cooperation between China and countries along the route. Duan and Duan, (2023) studied the oil and gas cooperation between China and Central and North Asian countries in the “Belt and Road Initiative”, affirmed the potential of oil export cooperation with Central and North Asian countries, and gave suggestions for strengthening midstream and downstream cooperation in the oil industry.
The above pieces of literature show that regional cooperation strategies are indeed a common choice in the oil industry, and adopting a cooperation strategy can bring benefits and profits to the participants. This paper discusses the oil game problem from the perspective of evolutionary games, considering the possibility of participants choosing cooperative strategies and the possibility of further benefits when both parties choose cooperative strategies simultaneously.
From the perspective of sanctions between oil exporting regions, Zhou et al. (2022) found that as the United States has become the world’s largest exporter of crude oil, the competition intensity of emerging crude oil exporters is gradually increasing, with the potential for intense export competition between traditional and emerging exporters. Behar and Ritz (2017) studied the competition between OPEC countries and US shale oil in oil exports and found that competition for market share among oil exporting countries will increase global oil exports and lead to significant fluctuations in oil prices. Kisswani et al. (2022) analyzed the competition between OPEC and non-OPEC countries and revealed that the oil exports of non-OPEC member countries strongly affected the oil exports of OPEC member countries. In the short term, the increase in non-OPEC oil production will lead to a decrease in OPEC oil production; however, in the long term, the increase in non-OPEC oil production will also lead to a further increase in OPEC production.
From the perspective of sanctions between oil-importing regions, Zhang et al. (2014) used complex network theory to study the competition between oil-importing countries in the Asia-Pacific region. Zhou et al. (2022) found that the competition center for crude oil imports has shifted from Europe and the United States to the Asia-Pacific region, and is likely to continue to shift to developing regions based on a complex network model. Hao (2023) also used complex network theory to analyze the pressure network evolution law of crude oil import trade from 2000 to 2020. They found that China is under increasing competitive pressure from Germany and the Netherlands in Russia. It is suggested that crude oil importing countries expand the global circle of trusted trading partners to improve the supply stability. The result showed a clear relationship between competition intensity and geographical location. Different regions have different competition strategies, but only by achieving diversified supply and expanding the globally trusted trading partner circle can they gain an advantage in oil competition.
From the perspective of sanctions between oil regions, Zheng et al. (2022) used a complex network theory and failure model to simulate the impact of sanctions on oil trade on the global energy trade pattern. They found that oil sanctions would cause oil exporters such as Russia to shift their export focus to Asian countries, and oil sanctions would also improve the energy resilience and trade efficiency of European countries. Nguyen and Do (2021) studied the impact of economic sanctions and counter-sanctions on Russian oil trade and found that economic sanctions harmed Russia’s oil export interests while counter-sanctions harmed the interests of European Union agricultural product imports. The reduction in import and export quotas proves that implementing sanctions and counter-sanctions harms participating countries. Nakhli et al. (2021) used the Dynamic Stochastic General Equilibrium Model (DSGE) with the New Keynesian approach model to study the sanction activities of multiple countries on Iran’s oil exports. They found that oil sanctions will reduce other countries' economic and technological investment in Iran, ultimately decreasing oil production. Decreased government oil revenue will increase the government’s printing and coinage intensity, ultimately leading to inflation. As a country struggling to formulate a counter-sanctions strategy, oil sanctions will greatly affect Iran.
The above literature shows that adopting a confrontational or sanctions strategy is a common game strategy for participants. In order to obtain benefits, participants have the possibility of choosing sanctions strategies or making decisions to diversify their sanctioned intensity. This paper uses the method of evolutionary game to explore the problem of oil game, not only considering the benefits and losses obtained by the participating regions when making sanctions strategies and the possibility of countermeasures when the regions are sanctioned but also considering the possibility that both regions are unwilling to destroy existing cooperation.
Most of the above literature focuses on cases where regional cooperation or sanctions strategies have been chosen, but few papers explain that decision-makers will evolve strategies based on different situations. In addition, little literature defines the boundaries of interregional cooperation strategies and sanctions strategies. Therefore, this paper uses the method of evolutionary game to study the situation in which different strategies will be adopted in the oil game between regions, which further enriches the research in the oil field. The uniqueness of this paper compared to other studies is summarized in Table 1 below.
3. Evolutionary game analysis
This section discusses whether two oil regions, Region 1 and Region 2, will impose sanctions on each other’s oil products in future trade. Furthermore, constructing an evolutionary game model analyzes the boundary of cooperation and sanctions strategies adopted by the two regions in international oil trade.
3.1 Model assumptions
According to the stable evolution strategy proposed by Smith and Price (1973), the model adopted in this game is a two-party evolutionary game model. Evolution game deems that the main body participating in the game is bounded rationality, and the main body participating in the game does not need to have omniscience and omnipotence. However, the behavior choices of both parties will be adjusted and changed continuously to obtain more benefits, eventually evolving to a stable point.
The main body of the game in this model is Region 1 and Region 2. Both regions have the possibility of choosing a “sanctions” strategy or a “cooperation” strategy. In this paper, if one chooses the “sanctions” strategy, one will choose the means of economic sanctions against another region.
Furthermore, the probability of choosing the “sanctions” strategy in Region 1 is y, so the probability of choosing the “cooperation” strategy is 1-y. The probability of choosing the “sanctions” strategy in Region 2 is x, so the probability of choosing the “cooperation” strategy is 1-x.
When deciding whether to use the sanctions strategy between the two regions, their behavior and decision-making are aimed at improving economic benefits, which means that the sanctions strategies in this paper are all economic sanctions. Refer to Nguyen and Do (2021) for research on economic sanctions. In this paper, the sanctions strategy refers explicitly to increasing the tax rate on the other region’s imported oil and oil products, and reducing the amount of oil or oil products sold. The gains and losses in this game only involve the trade of oil and oil-related products between the two regions.
Region 1 is where crude oil is imported, and Region 1 purchases crude oil from Region 2. After processing crude oil, various oil-processed products obtained are sold to Region 2. Region 2 is where crude oil is exported. Region 2 sells crude oil to Region 1 and purchases finished processed oil and oil products from Region 1. For example, in the international oil trade between China and Russia, China’s largest oil supplier, China imports crude oil from Russia as a crude oil importer and exports oil products, such as lubricants, to Russia [7].
When Region
Referring to the study of Xin and Zhang (2023), the region will improve its oil exploration, mining, processing, transportation, storage, and obtain benefits from it. If the region is sanctioned, the speed and efficiency of development will be reduced due to the sanctions, resulting in reduced benefits. Assuming that the benefit obtained by Region
Referring to the study of Vatansever (2020), if Region 1 and Region 2 choose the “sanctions” strategy at the same time, the behavior of both parties at this time will reduce the trading relationship between each other and may further deteriorate the trade. For example, trade cooperation between regions may cancel existing projects or even affect other normal agreements to “punish” opponents. At this time, the trade conflict losses between the two regions is
Referring to the study of Yang et al. (2021), if both Region 1 and Region 2 choose the “cooperation” strategy, the behavior at this time can be regarded as a friendly relationship between the two sides, and there may be further cooperation and win-win between the two regions. For example, agreements can be reached quickly between the two places, and cooperation projects can be further expanded. At this time, the benefits of in-depth cooperation between the two regions is
The parameters involved in the model and the meanings are shown in Table 2.
3.2 Establishment of profit matrix
Based on the above assumptions, the payoff matrix for Regions 1 and Region 2 regarding whether to adopt sanctions strategies can be obtained, as shown in Table 3.
Based on the research of Friedman (1991), this paper can use the Jacobian matrix to verify whether the stable point formed by solving the game between the two sides is a stable point strategy.

Figures 1 and 2 are the schematic diagrams of the evolution of the game in various cases. The evolutionary schematic diagrams can express the evolution of the subjects participating in the game in different cases when choosing sanctions or cooperative strategies in different situations during the oil game, and visualization of the meaning and trend of stability in different cases in Table 2.
According to the evolutionary stability strategy calculated and analyzed in Table 2 under different cases and the evolutionary schematic diagram of Figures 1 and 2, the following 6 propositions can be obtained.
Combining Case1, Case2, and Case3, it is found that the evolutionary stable points are all (0,0) points. This indicates that when both Region 1 and Region 2 adopt sanctions strategies, if the net benefits obtained are less than the benefits
Combining Case4, Case5, and Case6, it is found that the evolutionary stable points are all (1,1) point. This indicates that when both Region 1 and Region 2 adopt sanctions strategies, if the net benefits obtained are greater than the trade conflict losses
For example, Canada is the largest source of energy imports for the United States, accounting for 27% of US energy imports in 2019, with crude oil accounting for 91% of imported energy [9]. In addition, the proportion of oil imported by the United States from Canada exceeds 51% of its total oil imports [10]. It can be seen that the United States is highly dependent on Canada in various energy imports, and there is a high willingness to cooperate between the United States and Canada. Just as the two regions have launched and signed numerous oil cooperation projects and contracts, once a trade conflict arises between the two regions, it will cause huge losses, so both sides tend to adopt a cooperation strategy. In comparison, the United States and Iran have less oil trade cooperation. Iran’s oil production is mainly transported to Syria, China [11], etc. The United States mainly imports oil from regions such as Canada, Mexico, and Russia, etc [12]. Therefore, in the event of a trade conflict between the two regions with less cooperation on oil projects, the losses caused by the trade conflict are lower, but the benefits brought by sanctions are higher, motivating them to adopt a sanctions strategy.
Combining Case8, Case9, and Case10, it is found that the evolutionary stable points are all (0,1) point. When the net profits obtained by Region 1 adopting a sanctions strategy is greater than the in-depth cooperation benefit
For example, the United States has adopted unilateral sanctions against Venezuela, banning trade in Venezuelan oil and products related to the oil industry chain [13]. This is because the United States has adopted a policy of unilateral sanctions against Venezuela, which has caused the oil price to drop rapidly. This has greatly benefited American business giants such as Chevron and enabled the United States to obtain huge benefits [14]. At the same time, it has also consolidated the position of some non-economic areas. Such sanctions are far more beneficial than in-depth cooperation between the two regions. However, Venezuela, as an oil exporting country, its economic resources are completely dependent on oil exports, and the economic benefits of the Venezuelan government, which has been cut off from oil exports, have plummeted but still hopes to maintain a cooperative relationship with the United States. This is because Venezuela cannot bear the huge losses caused by the trade conflict and hopes to be still able to guarantee that some existing cooperation projects will not be further affected [15], thus causing the situation of unilateral US sanctions against Venezuela.
In this situation of economic trade, sanctioners tend to choose unilateral sanctions to seek benefits. As the sanctioned region, if it wants to eliminate the dilemma of unilateral sanctions, it should choose to make more far-sighted interest exchange behaviors. For example, sanctioned region can choose unilateral direct sales instead of selling oil through the market. Although this move makes the sanctioned give up some immediate benefits, it can allow the sanctioner to gain certain benefits and increase the losses of trade conflicts
Combining Case11, Case12, and Case13, it is found that the evolutionary stable points are all (0,1) point.The net profits obtained by Region 1 adopting a sanctions strategy is less than the trade conflict loss
The results of Case7 well confirm the conclusion drawn by Case1 ∼ Case6, and their evolutionary stability points are (0,0) and (1,1). When
On the one hand, the results of Case14 verify the conclusion of Case8∼ Case13, where the evolutionary stable point is

5. Conclusion
In this paper, the game matrix of Region 1 and Region 2 is established, and the trace and determinant of the Jacobian matrix are solved by using the obtained dynamic replication equation, and whether the equilibrium point of the evolutionary game is an evolutionary stable point is judged according to its positive and negative. The study finds that the evolution trend of the game between the two regions mainly depends on the relationship between the net profits they obtained by adopting sanctions strategies, the losses of trade conflicts between the two regions, and the benefits of in-depth cooperation between them. It is that: (1) When the benefits of in-depth cooperation between the two regions are higher than the net profits obtained by Region 1 and Region 2 adopting sanctions strategies, the two regions will choose cooperation strategies simultaneously. (2) When the trade conflict losses between the two regions are lower than the net profits obtained by Region 1 and Region 2 adopting sanctions strategies, the two regions will choose sanctions strategies simultaneously. (3) When the net profits obtained by adopting a sanctions strategy is lower than the benefits of deep cooperation between the two regions, and while another region adopts a sanctions strategy, the net profits obtained is higher than the trade conflict losses between the two regions, there will be unilateral sanctions where one side sanctions and the other side does not.
Based on the above evolutionary results, several meaningful insights can be drawn: (1) Participation in the oil game between the two regions should prioritize the long-term benefits of deep cooperation. Policy makers should focus on long-term benefits rather than just short-term gains. When the benefits of in-depth cooperation between the two regions are greater than the net profits obtained from sanctions strategies, it will give the two regions a greater incentive to choose oil cooperation trade. Therefore, policy makers need to conduct a comprehensive threat and risk assessment, considering the possible long-term impact of cooperation, such as sustainable profit growth and more opportunities for deeper cooperation. (2) The oil game between regions should weigh the benefits and risks. Policy makers need to fully consider the potential trade conflict losses. For example, oil cooperation projects that have been signed and oil-related industrial chain cooperation will collapse with the implementation of sanctions strategies. As the losses of trade conflicts between the two regions increase, the cost of choosing a sanctions strategy increases, thereby reducing the likelihood of both parties choosing sanctions strategies. (3) Flexible response to the possibility of unilateral sanctions in the interregional oil game. If one of the two parties involved in the oil trade is a strong party that can make huge profits through the sanctions strategy, and the other is a weak party that is highly dependent on each other’s products or have difficulty in improving the competitiveness of its own products, the situation will evolve into a unilateral sanctions situation where only one party adopts the sanctions strategy. At this time, the weak party should flexibly adopt measures to get rid of unilateral sanctions. For example, a weak party can give up some of its current interests in exchange for opportunities for in-depth cooperation in the future. Besides, it should endeavor to expand its trade cooperation relations and establish a more stable cooperative relationship with the strong party. (4) Policy makers can strengthen regional risk response capabilities. Participating regions in the game pay close attention to the possibility of sanctions and cooperation between the two regions in real time by establishing corresponding management organizations and formulate different response methods. Assessing the possibility of current sanctions and cooperation in a quantitative way and considering the risks and benefits that different strategies may bring will help regions adjust decision-making choices and response methods in real time.
This paper analyzes the relationship between cooperation and sanctions in oil trade between the two regions, and future research can be further explored. First, this paper only considers the oil game between the two regions. In fact, in the oil game between the two regions, there are often the participation and constraints of third-party organizations, which makes the game complicated. Therefore, future research can build a tripartite evolutionary game model in which two regions and a regulator coexist to further explore the interregional oil game. Besides, this paper considers the influence of various parameters on the current evolutionary game. In fact, there are often disturbances from emergencies in the oil game. In the future, it can also be expanded to study the decision-making of participating in games under emergencies. Finally, the game in this paper only involves the impact on oil interests. In fact, there are also cooperation with other products, the intervention of competitors, and the emergence of alternative products, these parameters may dynamically influence the evolutionary pathways over time, and such issues will provide ample challenges for further research.
