Economy of Vietnam
Until the French colonization in the mid-19th century, Vietnam's economy had been mostly agrarian, subsistence-based and village-oriented. French colonizers, however, deliberately developed the regions differently as the French needed raw materials and a market for French manufactured goods, designating the South for agricultural production as it was better suited for agriculture, and the North for manufacturing as it was naturally wealthy in mineral resources. Though the plan exaggerated regional divisions, the development of exports—coal from the North, rice from the South—and the importation of French manufactured goods stimulated domestic commerce.
Hmong people
Vietnam, where their presence is attested from the late 18th century onwards, is likely to be the first Indochinese country into which the Hmong migrated. During the colonization of 'Tonkin' (north Vietnam) between 1883 and 1954, a number of Hmong decided to join the Vietnamese Nationalists and Communists, while many Christianized Hmong sided with the French. After the Viet Minh victory, numerous pro-French Hmong had to fall back to Laos and South Vietnam.
At the 2009 national census, there were 1,068,189 Hmong living in Vietnam, the vast majority of them in the north of the country. The traditional trade in coffin wood with China and the cultivation of the opium poppy – both prohibited only in 1993 in Vietnam – long guaranteed a regular cash income. Today, converting to cash cropping is the main economic activity. As in China and Laos, there is a certain degree of participation of Hmong in the local and regional administration. In the late 1990s, several thousands of Hmong started moving to the Central Highlands and some crossed the border into Cambodia, constituting the first attested presence of Hmong settlers in that country.
