Before the Manila meeting, the Malayan Government had set 31 August as the date on which Malaysia would come into existence (coinciding with Malaya's independence day celebrations of 31 August). However, at the Manila negotiations, it was persuaded by the Indonesian and Philippine Governments to postpone Malaysia's inauguration until 15 September 1963 by which time a UN mission was expected to report on whether the two Borneo colonies supported the Malaysia proposal. However, following the conclusion of the Manila talks, the Malayan Prime Minister Tunku Abdul Rahman announced that the proposed Malaysian state would come into existence on 16 September 1963, apparently irrespective of the latest UN report.
