12 October 1968
The Secretary-General of the Supreme African Sports Council, Jean-Claude Ganga, said he would admit white South Africans to the African Games provided that competitions in South Africa are held without racial discrimination. Eight years later (1976), Tanzania refused to go when the International Olympic Committee (IOC) ignored demands for New Zealand to be expelled because their rugby team was touring the banned South Africa. On the eve of the opening ceremony, Ganga called a boycott of 21 other African countries, joined by Iraq and Guyana
