China and Russia reached the final agreement in 2005 over their eastern border, putting an end to 40 years of negotiation. They exchanged ratification documents by their parliaments agreeing to share around fifty-fifty the last disputed land. China and Russia share a 4300- kilometer-long border. Peaceful settlement of the border issue was a great achievement that all disputes between the two neighbors regarding the border issue were in history. By solving the border issue through peaceful consultation, Russia and China have set a good example for other countries in setting similar disputes.
This article is aimed at demonstrating the peaceful settlement of the border issue was resulted in the normalization of political relations between Russia and China. The inconsistent claim by China that its former land which had been seized by Zsar Russia should be restored, was actually a propaganda for altering its asymmetrical relationship with Russia. This perspective provides effective explanation of China's declaration that it had no more territorial problem with Soviet at the time of concluding the Sino-Soviet “Good Neighbor Treaty", despite their long history of border disputes. In other words, the Sino-Soviet border disputes were not about territory but rather the different their political relations.
Yet Russians remain suspicious of China's longer term intentions. Chinese historians continue to denounce the current borders as unfair and imposed on China by Russia in the 19th century, and Chinese children are still being taught in school that Russia took away the Far East from China by force. In conclusion, paying due regard to altering of the Russo-Chinese relationship, we must watch attentively the border issue.
