In July 1963, a tripartite meeting was held in Manila between Indonesian president Sukarno, Philippines president Diosdado Macapagal and Malayan Prime Minister Tunku Abdul Rahman. The three heads of state signed an agreement known as the Manila Accord where Indonesia and the Philippines stated that they would welcome the formation of Malaysia "provided the support of the people of the Borneo territories is ascertained by an independent and impartial authority, the Secretary-General of the United Nations or his representative," and provided further that "the inclusion of North Borneo as part of Malaysia would not prejudice either the claim or any right thereunder" by the Philippines to the territory.
