In October 1926, in response to the government's concern for overseas community affairs, the Overseas Community Affairs Council (OCAC) was established directly subordinate to the Nationalist Government. In December 1931, the OCAC Organic Act was enacted. This measure placed the OCAC under the Executive Yuan. The National Assembly enacted the Constitution of the ROC in December 1946, listing overseas compatriot affairs among the nation’s “fundamental national policies” and stipulating that the nation should protect and assist overseas compatriots in terms of economic development.
In December 1981, the number of Deputy Ministers was changed from two to two or three based on a revision to the OCAC Organic Act. In response to the restructuring of the Executive Yuan, the Act was further revised in September 2012.The current organization includes a minister, a deputy minister, a vice minister and five departments, as well as five offices. Additional divisions include Overseas Community News Agency and Legal Affairs Committee.
In March 1985, the OCAC's first Culture Center of Taipei Economic Cultural Office (TECO) was established in San Francisco, U.S.A. to serve overseas compatriots. The number of culture centers of TECO has increased to 16 over the years, and now they can be found in the U.S., Canada, Brazil, the Philippines, and Australia.
