The United States and Russia strove hard to harvest the Mid-Eastern Europe as respective sphere of influence in the past two years. To get national safeguard，Mid-Eastern European countries generally turned to the USA while abandoning Russia. Some of them even joined the America’s strategy of containing Russia and agreed to deploy TMD in their territories. They lived on the U.S. in military while on EU in economy. When a dispute emerged between the U.S. and EU，they were inclined to stand for the former and some of them further viewed it a chance to “press” EU. The frictions between EU and Russia mainly resulted from Mid-Eastern Europe. Energy served as a political instrument for Russia and the Mid-Eastern European countries. The membership of EU to some extent lifts the status of those Mid-Eastern European countries in EU.
