This is if Russia can continue to use the gas, I think they will dominate just by this advantage. They are however not the super dominant in Asia, there is always China that has higher advantage over them. China also have the gas supply of their own, not as big as Russia but China has the technology. If the two will start a quarrel I think the unity of both can change. As for now, Its Russia who will win against the West due to the gas dependency of EU.
It is typical US foreign policy to try to quarrel with neighboring countries in order to stir up tensions in the region. Why should Russia quarrel with China if it is possible to live as neighbors and strengthen mutually beneficial cooperation? This is our common continent, along with India, Europe and the Middle East. The US has spread its toxic influence around the world and it will soon come to an end. We can live in peace and act together when the US and Western Europe give up their unfounded claims to exclusivity and superiority over other peoples. Russia can become the new guarantor of global security, it has enough power for this and enough self-control not to use this power in its own selfish interests. Because Russia is the largest and potentially the richest country in the world, with a huge abundance of natural resources. She does not need to plunder other nations in order to prosper.
Its what they do. China vs India were tried too which they flamed it too much in the borders which there was a time they were actually shooting incident. But then India and Russia are favorable to Chinese projects in their region so they are more inclined to make friends, every country from east going to Africa I think will benefit when they make friends with China.
However Russia may not be a guarantor of global security. China has a diplomatic way of doing things which could led to serious path. These two are in tandem but many would truly see its China that is more advance.
