What were three policies instituted by the United Nations to put pressure on South Africa to end apartheid?

The United Nations implemented several key policies to pressure South Africa to end apartheid, including the establishment of an embargo on arms sales to the country in 1963, which aimed to restrict military support for the apartheid regime. In 1977, the UN General Assembly called for comprehensive economic sanctions against South Africa, urging member states to withdraw investments and trade. Additionally, the UN recognized the African National Congress (ANC) as the legitimate representative of the South African people, providing it with moral and political support in its struggle against apartheid.
