rice and rubber were the main items of export. Domestic and foreign trade were centered around the Saigon-Cholon area. Industry in the South consisted mostly of food-processing plants and factories producing consumer goods. When the North and South were divided politically in 1954, they also adopted different economic ideologies: socialism in the North and capitalism in the South. Destruction caused by the Second Indochina War from 1954 to 1975 seriously strained the economy. The situation was worsened by the country's 1.5 million military and civilian deaths, and the subsequent exodus of 1 million refugees, including tens of thousands of professionals, intellectuals, technicians and skilled workers out of the millions of war refugees. 1976–1997 The government's Second Five-Year Plan (1976–1981) aimed for solid high annual growth rates in industrial and agricultural sectors and national income and sought to integrate the North and the South, but the goals were not attained. The economy remained dominated by small-scale production, low labor productivity, material and technological shortfalls, and insufficient food and consumer goods. The more modest goals of the Third Five-Year Plan (1981–85) were a compromise between ideological and pragmatic factions; they emphasized the development of agriculture and industry. Efforts were also made to decentralize planning and improve the managerial skills of government officials. After reunification in 1975, the economy of Vietnam was plagued by enormous difficulties in production, imbalances in supply and demand, inefficiencies in distribution and circulation, soaring inflation rates, and rising debt problems. Vietnam is one of the few countries in modern history to experience a sharp economic deterioration in a postwar reconstruction period. Its peacetime economy was one of the poorest in the world and had shown a negative to very slow growth in total national output as well as in agricultural and industrial production. Vietnam's gross domestic product ( GDP) in 1984 was valued at US$18.1 billion with a per capita income estimated to be between US$200 and US$300 per year. Reasons for this mediocre economic performance have included severe climatic conditions that afflicted agricultural crops, bureaucratic mismanagement, elimination of private ownership, extinction of entrepreneurial classes in the South, and military occupation of Cambodia (which resulted in a cutoff of much-needed international aid for reconstruction). From the late 1970s until the early 1990s, Vietnam was a member of the Comecon, and therefore was heavily dependent on trade with the Soviet Union and its allies. Following the dissolution of the
