The OECF, a Japanese government development financial institution, provides developing countries and areas with grants and long-term, low-interest loans. As a result of difficulty in distinguishing between the Fund and the Export-Import Bank of Japan, a 1975 reorganization put OECF in charge of all direct loans to be made as official development assistance (ODA) with the grant element of 25 percent of more. The Fund was created in 1961; headquarters are in Tokyo, Japan. See: Export-Import Bank of Japan Japan International Cooperation Agency
