text: UNITED NATIONS S Distr. GENERAL s/17472 18 September 1985 ORIGINAL: ENGLISH LETTER DATED 18 SEPTEMBER 1985 FROM THE PERMANENT REPRESENTATIVE OF ANGOLA TO THE UNITED NATIONS ADDRESSED TO THE PRESIDENT OF THE SECURITY COUNCIL Upon the instructions of my Government, I have the honour to draw your attention to the most recent violent acts of armed aqqtession committed aqainst the people and territory of the People's Republic of Anqola by the racist regime in South Africa; the racist Armed Forces of the apartheid t&qime, once aqain crossed the soveteiqn border of the People's Republic of Anqola on 16 September 1985 and enqaqed in acts of wanton destruction and brutality against Anqola. This militarv adventurism and expansionism of racist South Africa under the pretext of non-existent "pre-emptive strikes" of Namibian nationals, is obviously desiqned to draw international attention away from the conflaqtation that is enqulfinq the racist apattheld minority t6qime in Pretoria. The entire world has at last finally tecoqnized the evils of apartheid and its effects not only on the inhabitants and disenfranchised nationals of South Africa, but on the southern Africans as a whole. South Attican state terrorism against its sovereign neighbours is hut the external manifestation of its internal state terrorism against Its ma)otity inhabltants. Such deviousness can no longer tool the international community. My Government wishes to brinq this heinous apartheid sttateqy to the special attention of those who are late but welcome supporters of the national and international struqqle against apartheid. My Government also wishes to focus international attention, in particular at the beqinninq of the fortieth session of the United Nations General Assembly, of the international community on the violation of international law and of Anqola's sovereignty and tectitotial inteqtity by a state which has heen expelled from the General Assemblv. 
analysis: The text appears to be a diplomatic letter from the Permanent Representative of Angola to the United Nations, expressing concerns about the recent military actions of South Africa against Angola. The letter highlights the violation of international law, sovereignty, and territorial integrity of Angola by South Africa. The tone is formal, official, and critical of the apartheid regime in South Africa. Given the focus on international relations, territorial disputes, and human rights, it is likely that the text falls under the category of international relations.
