Sino-Russian relation has been developing smoothly on the whole after the disintegration of the Soviet Union.In recent years,following common efforts by the two governments and peoples,Sino-Russian relation is advancing and deepening continuously,and “Sino-Russian strategic partnership relation” has been established.However,“Chinese Threat” emerges in Russia as well as in western countries.Why the concept of “Chinese Threat” is advocated in Russia is that some Russians are influenced by Russian historical memory,the widening gap between China and Russia in their power,China's misadministration and western media's misleading exaggeration.The concept is imagined in three threats of China's rise,China's immigrant and China's possible collapse.Based on the concept of “harmony” in Chinese traditional culture,this paper analyses Chinese concept of “harmony” from the angle of history and reality,and concludes that China,in history,was a reserved nation pursuing peace and,at present,selects a diplomatic strategy of peaceful rise and co-establishing a harmonious world.The paper refutes "Chinese Threat" in Russia and argues that China's peaceful rise will pose no threat to any country including Russia.
