‘A global concept’ describes how scattered communities have formed new bonds of solidarity. Decolonization caused new kinds of migration to occur. Anti-Chinese sentiment in Indonesia and during the Vietnam War has led to displacement of Chinese immigrants. The same has happened to Indians in Burma, Sri Lanka, Fiji, and Suriname; and South Asians in Idi Amin's Uganda. The United Nations protects many of these refugees, and global awareness is higher than ever. Whilst the era of unrestricted mass migration is over, technology has changed the way diasporic communities communicate and travel. Many countries actively promote the inclusion of diasporas in national cultures, and welcome returning migrants.
