This article describes the relationship of the Centro Mexicano de Escritores, Mexico's most important writing centre in the second half of the twentieth century, to the US foundations that funded it. The Centre was founded by a North American writer, Margaret Shedd, with the financial support of the Rockefeller Foundation. The Rockefeller Foundation understood the Centre as a ‘Pan-American’ effort to improve relations between the United States and Mexico by bringing its writers closer together. Later, there were also contributions from two CIA fronts, the Farfield Foundation and the Congress for Cultural Freedom, to the Centre and its star graduate, Juan Rulfo. However, this article argues that none of the US foundations realised the ambitions that they had for the Centre. Through a process of ‘Mexicanised Americanisation', a project that had elements of Yankee cultural imperialism produced instead one of the world's finest writing centres, but without any clear political benefit for the United States.
