The appearance of colored peoples, and blacks in particular, in Chinese propaganda posters always has been problematic. Before the CCP grasped power, the only attention devoted to colored peoples in Chinese art was of a negative tone. Once the PRC was established, however, this attitude changed. Now that racial problems were seen as class problems, China increasingly discovered similarities between its own traumatic experiences with 'white imperialism' and those of other victimized 'colored' people in the world. It was time to downplay the traditional and deeply ingrained feelings of superiority. One of the first official steps to gain credibility as a supporter of the oppressed was taken in September 1950, when the Chinese lodged an official protest against the policy of apartheid in South Africa. Africans soon became regular guests in Beijing, where they were entertained at parties and met with the highest state leaders. By the late 1950s, many delegations had passed through Beijing and Zhongnanhai. But the Chinese did not actively spread the gospel of revolution and national liberation yet. They merely positioned themselves as a model that needed to be followed to gain independence.
