One of the worst things that comes to my mind in the near future is that China and Russia will form somekind of partnership.Because after the collapse of Soviet Union they dont have that kind of ideologigal rivalry between them.Russia is in lot more better terms with China then Japan, because Russia and Japan have had an feud of Kuril (spelling?) Islands since WWII.Infact Russia is the only major country in the world that sells weapons to China.
Imagine if these too would join their forces with Russias huge natural resources and Chinas human resources.
