Heng Samrin
The First Five-Year Program of Socioeconomic Restoration and Development (1986–90), or First Plan, originated in February 1984, when the heads of the state planning commissions of Vietnam, Laos, and Cambodia met in Ho Chi Minh City (formerly Saigon) and agreed to coordinate their 1986 to 1990 economic plans. Heng Samrin formally announced Cambodia's plan in his political report to the congress.
