Did economics or ethnic persecution drive the Hoa exodus?

The short answer

• Punishing the old regime. Hanoi treated those linked to the Saigon government as a danger to the revolution, and re-education was its instrument. Detention without trial for years, the loss of property and the exclusion of their children from education left these families with no future in Vietnam. Many who had stayed in 1975 because they could not leave decided by 1978 that leaving was worth the risk of the sea.
• Socialist transformation of the South. The collectivisation of farming, the closure of private businesses and the forced move of city dwellers to New Economic Zones were meant to build a planned economy, and they impoverished and alienated much of the urban South. Shortages worsened after floods and failed harvests in 1977–78. Policies aimed at a class created refugees across that class, from small traders to doctors.
• The break between Vietnam and China. Great-power rivalry turned a minority into suspects. By 1978 Vietnam had aligned with the Soviet Union, joined its economic bloc and gone to war with Cambodia, China’s ally. China cut aid and protested the treatment of the Hoa, and Hanoi came to see its ethnic Chinese as a security risk. Great-power rivalry thus turned a domestic minority into the main source of refugees, and it would lead to open war in February 1979.
• Terror in Democratic Kampuchea. The Khmer Rouge programme of forced labour, purges and the elimination of class and ethnic enemies killed about a fifth of Cambodia’s people between 1975 and 1979. Its sealed borders kept most victims inside, while purges in the eastern zone in 1978 drove some cadres and civilians into Vietnam. The catastrophe built up a vast hidden displacement that would pour toward Thailand once the regime collapsed.

What it changed

The boats multiply. The exodus became a mass movement by sea. Departures grew from a few thousand a year to tens of thousands a month by early 1979, many in vessels that officials had sold or licensed. The arrivals overwhelmed camps in Malaysia, Hong Kong, Indonesia and Thailand, and the next chapter shows how those first-asylum states reacted when they believed they were being made to absorb another country’s minority.

War with China. China’s anger over Cambodia and the Hoa led to its invasion of northern Vietnam in February 1979. The war sharpened suspicion of the remaining northern Hoa, most of whom then left by sea for Hong Kong, the arrow that chapter 9 draws along the coast past Hainan. A war between two communist states thus became, at one remove, a refugee crisis for a British colony.

Cambodia’s hidden displacement surfaces. The fall of the Khmer Rouge released a displacement that terror had kept hidden. When Vietnam’s army overthrew Democratic Kampuchea in January 1979, hundreds of thousands of starving Cambodians moved toward the Thai border. The famine and the border camps that followed, from Khao-I-Dang to Site 2, became the second great refugee crisis of the region, traced in chapters 10 and 11. Unlike the boat people, most of these Cambodians were kept at the border and never resettled.

Laos empties slowly. Laos emptied slowly across the Mekong, a river border that was easy to cross and hard to guard. About 360,000 people from Laos reached Thailand between 1975 and 1995, roughly one in ten of the population. Many Hmong in camps such as Ban Vinai resisted resettlement in the West for years, hoping to go home, and their fate under the 1989 plan of action is part of chapter 11. Their reluctance shows that resettlement, the West’s favourite solution, was not what every refugee wanted.
