Geopolitics has a huge impact on the oil and gas market. Beyond stable supply，the key geopolitical factor remains price trends. The United States has imposed sanctions on a number of energy-producing countries，and the U.S. government has not shied away from doing so to achieve its diplomatic and strategic goals，such as changing the regime of one producer and balancing the power structure of a certain region. The shale oil and gas revolution has made the United States the most important producer and exporter of oil and gas in the world，which has led to significant fluctuations in global energy prices. At times，the U.S. diplomatic strategy has driven up energy prices，exposing consumers to financial losses. Even in a trade war between China and the United States，energy has become a key factor in the game. It is safe to say that oil is a lever of us foreign policy. The strategic competition between China and the United States is intensifying，which leads to the influence of great power game on energy geopolitics are also growing. There are political and strategic considerations behind U.S. sanctions against Iran，Venezuela and other countries. Controlling some oil production areas is not only one of the goals of American foreign policy，but also an important means of American foreign policy. For China，we can match the U.S. in terms of energy consumption and production，but it is clear that our cognitive and operational capabilities need to be improved.
