In the past decade，the United States has successfully emerged as the world’s largest oil and gas producer and net energy exporter，which triggered a dramatic change in the global energy supply and demand pattern. At the same time，the pace of global energy transformation was accelerating due to the universal recognition of the urgency and importance of addressing climate change. After the Trump administration took office，the U.S. international energy strategy changed from pursuing of “energy independence” to pursuing of “energy-led”. The characteristics of energy as a tool of U.S. foreign policy are becoming more prominent. At present，the U.S.energy strategy in Central Asia is more committed to achieving geopolitical goals through energy diplomacy. Compared with the past，the United States has placed more emphasis on promoting low-cost new energy to generate electricity in Central Asian countries through corporate technology and private capital assistance. Simultaneously，the United States continues to encourage the diversification of oil and gas exports from Central Asian countries，but its focus has shifted from pushing the TAPI pipeline project to supporting the construction of the trans Caspian sea gas pipeline. In addition，U.S. energy diplomacy and water diplomacy are accelerating the integration in Central Asia，and the implementation of the governance model of energy food water linkage has become an important part of the US Central Asia energy strategy.
