The country joined the United Nations (UN) on 10 October 1975 by way of Security Council Resolution 375 and General Assembly resolution 3368.

The 1982 elections increased Pangu's plurality, and parliament again chose Somare as prime minister. In November 1985, the Somare government lost another vote of no confidence, and the parliamentary majority elected Paias Wingti, at the head of a five - party coalition, as prime minister. A coalition, headed by Wingti, was victorious in very close elections in July 1987.
