International Disputes
The PRC is in a number of international territorial disputes, several of which involved the Sino-Russian border. Although the great majority of them are now resolved, China's territorial disputes have led to several localized wars in the last 50 years, including the Sino-Indian War in 1962, the Sino-Soviet border conflict in 1969 and the Sino-Vietnam War in 1979. In 2001, the PRC and Russia signed the Treaty of Good-Neighborliness and Friendly Cooperation, which ended the conflict. Other territorial disputes include islands in the East and South China Seas, and undefined or disputed borders with India and North Korea.
