I really do not see Russia and China joing forces or working together. Russia may right now be giving this and that to the Chinese, but in the long run China is bad news for Russia. Why? Because just north of China is Siberia - literally millions of square miles of nearly unpopulated land teeming with natural resources, especially oil. What does China need? Space and oil. In the long run, Russia's interests lay with the only country that can help it and that has an interest in helping it, and that country is the United States. As long as Russia doesn't slip into a new dictatorship (which it may), Russia and the US will eventually drift towards cooperation and perhaps even a formal alliance because of the US's need for oil from somewhere other than the middle east and because of Russia's need for protection.
Russia is probably nervous about to many linkages with China..as she is well aware of Chinas intrigues and decpetions when tech and fabrication are concerned.
ie..some years ago..China pretended to be inept in fabricating the fuselage of the SU-27.
Later..Sukhoi learned that their techs were being plied with Booze,Girlies and coin.
all manner of *off the table goodies were schemed by China..especially in the computer suite dept of SU-27.
China is still liscensed to build SU-27's....yet Russia is aware that China has the details on the superior Sukhoi engines withheld..allong with modifications to the SU-27's computer suite....which had limitations according to the foreign sales contract.
ie..changing the computers targeting ability..increasing it from 4 tracks to 8.
Wonder if some Sukhoi techs ended up in a Gulag : )
I don't think there is harmony between Russia and the US. If Russian wants the same status as the american, they will conflict with the US even if they are democratic. They are just too big.
