Trans-Asian labour migration, a defining feature of Asian globalisation prior to 1940, comprised mainly Chinese and Indian emigration to Southeast Asia and was quantitatively and qualitatively as significant as European transatlantic migration. Although migrant workers were regarded as sojourners, they established diasporic communities across the region, particularly in Malaysia, Singapore and Thailand. After the Second World War and problems of decolonisation, unskilled labour migration came to a halt.
