renmin said:Actually, during those years when the two countries were allies, Russia did have a few military bases staioned in China (dont ask me where, I really dont know). Russia sent its top scientists to help China with arcitecture, military, civilian technologies. Many projects were started spending much money. But after Josef Stalin died, The next Soviet Leader, (this is in pinyin) He le xiao fu (who actually hated Stalin) took back all the scientists which canceled many unfinished projects which meens China just wasted ALOT of money. The Russian bases were also taken away. The russian leader also tried to boss China around. At the last straw, Mao ze Dong finally broke up with the Soviets. From this break up, China learned that no one should rely on someone else as what china had done and ended up spending much for nothing. Now that China and the Russians are close again including the fact that the two did the joint military exercise, I'm really not surprised Russia is building a base in China.
Port Arthur, before return of it to China, was major Soviet base. I think there were others in Manchuria, and of course Soviet volunteers operated from China during Korean War.
