However, rather than peaceful reunification, partition led to the Vietnam War. During this time, the People's Republic of China and the Soviet Union supported the North while the United States supported the South. After millions of Vietnamese deaths, the war ended with the fall of Saigon to the North in April 1975. The reunified Vietnam suffered further internal repression and was isolated internationally due to the continuing Cold War and the Vietnamese invasion of Cambodia. In 1986, the Communist Party of Vietnam changed its economic policy and began reforms of the private sector similar to those in China. Since the mid-1980s, Vietnam has enjoyed substantial economic growth and some reduction in political repression, though reports of corruption have also risen.
