Iso Freak thanx for great deal of information.. But what I understood from your reading is- Russia is so much concern about radical developement of Chinese mainly in weaponary power, and under any circumstances Russia along with Japan may not to let (strategically) China to fill power vacuum in South-east asia but isn't it true Russia has coorporate China with Strategic military modernization? But what I believe is Sino-Russian relation is based on thier common interests and their willingness to cooperate diplomatically against US policies that they see as unfriendly to their interest. The closer ties with Russia have already resulted in a strategic relationship that is designed to counter the influence of the US. But still based on this evidence Chinese supremacy cannot be overated.
