From Wikipedia article, "Africa Action" (accessed 10/22/2018):

The Africa Fund, founded in 1966, worked with American Committee on Africa to provide key support for independence movements throughout Africa. During the anti-apartheid movement, the Africa Fund became the "principal contact point for progressive trade unionists and politicians." They encouraged US firms and stockholders to divest in South Africa and published updated lists of U.S. companies involved there.
