The People's Republic of China (PRC) and the Democratic People's Republic of Korea (DPRK) established diplomatic relations on 6 October 1949, five days after the proclamation of the PRC. In 1950, China intervened in the Korean War through the People's Volunteer Army after the North Korean forces had been shattered by United Nations and United States forces, successfully ensuring North Korea's survival. In 1961, China and North Korea signed a mutual aid and co-operation treaty, which is currently the only defense pact China has with any nation. North Korea attempted to not take sides during the Sino-Soviet split, though relations deteriorated during the Cultural Revolution, leading North Korea to move closer to the Soviet Union. Though improving in the 1970s, the relations weakened after China refused North Korean plans to reinvade South Korea, after the Khmer Rouge victory at the Fall of Phnom Penh.
