Smaller Russia and Bigger China

Political events caused by the Ukraine crisis clearly indicated that not only the West but also China has taken the label of victory through acquiring new opportunities in Russia.  
Sudden economic sanctions against Russia, has forced Moscow to take emergency measures in various fields such as banking, the Caspian Sea and transactions (Gazprom).
It is obvious that the thirty-year Gazprom contract with China which exchanged cheap gas for preventing the collapse of the Russian economy was mostly in favor of Beijing. Beijing's tactic was evident in the case of Ukraine."Just watch the game and wait, then buy the loser card for a cheap price", actually as Russia gets weaker, it would need to attract China's support, and Beijing, as well gets a higher chance to acquire more political and economic gains in Moscow. But we should not forget that Washington has two rivals, the first one to be Moscow and the other is Beijing. So, although the White House is able to defeat Moscow in a costly competition with Kremlin, but China will achieve economic and political advantages from Russia to the amount of the costs that America pays in this game, therefore, China would be able to confiscate the game. 
The position that China would have in a Cold War between Moscow and Washington is similar to the state of West during the Iran-Iraq war. Thus, selling arms to both hostile parties, the West and even Israel (referred to Iran-gate) were weakening Tehran and Baghdad as the threatening elements in the Middle east as a result of the continuing the war.There is no doubt that White House should not ignore the policy of containment on Russia, but it is necessary to verify the tactic of the policy of containment by considering the fact of China. What is needed is that a power struggle should develop within Russia. As at the time of Boris Yeltsin there was such a quarrel in Russia and caused the Russian government's inefficiency in the arena of international politics. The formation of such a quarrel is provided with regard to the failure of Moscow and the damages to Russia as a result of the adventures of the Kremlin leadership. So by putting the burden of liability for failures on Vladimir Putin, it would be like a spark in a place full of carbon dioxide. On the other hand, when the West differentiates the fight against Putin's politics from the issue of competing with Moscow, has shown its good faith. Thus, without having to pay a competitive price against Moscow, the West can eliminate its rival.
