calling on all member states to impose a trade boycott against South Africa. In 1963, the UN Security Council called for a partial arms ban against South Africa, but this was not mandatory under Chapter VII of the UN Charter. Olympic participation Abdul Minty, who took over from Rosalynde Ainslie as the AAM's Hon. Secretary in 1962, also represented the South African Sports Association, a non-racial body set up in South Africa by Dennis Brutus. In the same year, he presented a letter to the International Olympic Committee meeting in Baden-Baden, Germany about racism in South African sports.

Its findings also pointed out that in order to be effective, a programme of sanctions would need the active participation of Britain and the US, who were also the main obstacle to the implementation of such
