Between 1992 and 2004, within less than a decade, China transitioned from a country that was self-dependent on petroleum to one which began relying heavily on imported oil resources[1]. This condition has remained unchanged since 1993, with projections of crude oil imports reaching 61% by the end of 2015[2]. Coupled with the fact that China’s urbanization level surpassed 50% in 2011[3], the problem of greater per capita demand for rapidly depleting energy resources has made China’s energy security issues an international concern. Scholars have noted that China’s aggressive stance on energy security policies is in contrast to its relatively weaker foreign policy agenda[4], a paradox that not only threatens other major oil-consuming countries such as the U.S., but also reveals the less often discussed lack of mutual political and historical awareness among key players in the energy market. The U.S. and China, two nations at the forefront of energy-related tensions, should especially emphasize a comprehensive overview of past energy security policies in both countries to achieve a more effective cooperation mechanism for guiding global energy diplomacy in the future.
