text: being brought effectively to book. 18. The racist regime of South Africa has yet again infringed the sovereignty and territorial integrity of Angola by launching a fresh act of aggression against that country. It has done so, as it has done so often in the past, even before the ink was dry on the last resolution of the Security Council on the subject, adopted barely 13 days ago. Resolution 571 (1985), unanimously adopted by the Council on 20 September last, had once again strongly condemned the racist regime of South Africa for its “pre- meditated, persistent and sustained armed invasions of the People’s Republic of Angola” as a “flagrant violation of the sovereignty and territorial integrity of that country, as well as a serious threat to international peace and secu- rity”. It had furthermore renewed the Council’s demand that South Africa “withdraw forthwith and unconditionally all its military forces from the territory of the People’s Republic of Angola, cease all acts of aggression against that State and scrupulously respect the sovereignty and territorial integrity of Angola”. The large-scale aerial bombardment unleashed by Preto- ria’s forces on 28 September, of which Mr. de Figueiredo has just apprised the Council, was South Africa’s arrogant but by now familiar response to the verdict of the Security Council. 19. At the Meeting of Ministers and Heads of Delegation of Non-Aligned Countries to the fortieth session of the General Assembly, held in New York on 1 October, a special communique [S/17.518, annex] was adopted reflect- ing the position of the Movement of Non-Aligned Coun- tries with regard to the acts of aggression committed by South Africa in the last few days. I would like to read into the records of the Council relevant excerpts from this communique: 
analysis: The text appears to be a statement from the United Nations Security Council condemning the actions of South Africa against Angola. It mentions the invasion of Angola's territory, the violation of its sovereignty and territorial integrity, and the threat to international peace and security. The language used is formal and diplomatic, indicating that the statement is likely a formal resolution or statement from the Security Council. Given the context, it is likely that the category is related to international relations, security, and conflict resolution.
