The tripartite free trade agreement brings together 28 member countries of COMESA, the East African Community (EAC) and the Southern African Development Community (SADC). While hostilities were pending in Angola, the parties met in New York and Geneva in June and August. Finally, on 20 July, all approved a framework agreement on the principles of a peaceful settlement in South-West Africa.  During the negotiations, South Africans were invited to release Nelson Mandela, an an ANC activist imprisoned, as a sign of goodwill, which was disputed.  A ceasefire was finally concluded on 8 August 1988. Mandela remained in prison until February 2, 1990, when South Africa lifted the ban on the activities of the ANC`s African National Congress.  Namibia is the latest to ratify the TFTA agreement and today the country`s High Commissioner in Zambia, Siyave Haindongo, tabled the ratification instrument to the chair of the tripartite task force Chileshe Kapwepwe, the secretary of COMESA. The agreement followed the proposed US link, which had been promoted several times by South Africa in 1984 and 1986 (UN session). Namibia was to gain independence on the terms set by South Africa, including multi-party democracy, a capitalist free market economy and a transition period. In 1981, Chester Crocker, assistant secretary of state for African affairs of the new US President Ronald Reagan, had developed a policy of liaison.
It conditioned South Africa`s approval on apartheid to relinquish control of Namibia and withdraw from Angola, in accordance with UN Security Council Resolution 435, to the withdrawal of its troops from Angola.   On September 10, 1986, Cuban President Fidel Castro accepted the principle of Crocker`s proposal. The South African government has also accepted the principle of the link; it proposed the concept at the 7th plenary session of the United Nations on 20 September 1986 (the Namibia question). Lusaka, Tuesday, February 25, 2020: The implementation of the tripartite free trade agreement is now in sight after an increase in the number of countries that will ratify and ratify the agreement. Eight countries have ratified the agreement to date and there are six left to reach the required threshold of 14 for the agreement to enter into force. The Tripartite Free Trade Area (TFTA) is a draft free trade agreement between the Common Market for East Africa and South Africa (COMESA), the Southern African Development Community (CDAA) and the East African Community (EAC).  After Piet Nortje`s book 32 Battalion, South Africa introduced its new secret weapons, the G5 and G6 caped guns, during this campaign. Guns can fire a projectile of more than 40 kilometers with high accuracy.
The guns were used to halt Cuba`s advance southwards and succumb to the spectre of a further prohibitive escalation of weapons between two medium-sized military powers. South Africans say Cuba`s new weapon has stoked fears of more casualties in a war where The number of Cuban deaths has increased tenfold.
