Deng era

See also: Sino-Vietnamese War
Soon after Deng became the Paramount Leader of China, the Vietnamese invaded Cambodia and ended the genocide by defeating the Khmer Rouge in January 1979. The People's Republic of Kampuchea was then established. In order to counter the power of Soviet Union and Vietnam in Southeast Asia, China officially condemned the Vietnamese invasion and continued its material support to Khmer Rouge. In early 1979, China launched an invasion of Vietnam to retaliate against Vietnam's invasion of Cambodia.

Deng was convinced by a conversation with Singapore's prime minister Lee Kuan Yew to limit the scale and duration of the war. Following the one-month war, Singapore attempted to serve as a mediator between Vietnam and China on the Cambodian issue.
