Positive Correlation between Sino-Russian Oil and Gas Cooperation and 'Russian Leverage'

引用

China Oil & Gas 2018年第4期25卷 34-38页

作者： Liu Guizhou cnodc. Ltd

It is well known that since the disintegration of the former Soviet Union, Russia has suffered detrimentally as a result of strategic pressure from the United States and Europe. After over ten years of concession and silence,Russia with Putin as the core counterattacks, deploying stunning tactics one after the other. These not only set up'loss limits',but also protected and won Russia's interests to the greatest extent, such that Russia not only won respect but also gained benefits. These stunning tactics are called'Russian Leverage'.
