Australia referred the conflict to the United Nations Security Council (UNSC) on 30 July 1947, naming the Netherlands as the violators of the peace. Later, Australia raised the matter of Indonesia's decolonisation in the United Nations. Two days later, the UNSC ordered a cease-fire and established a committee to broker a truce and a renewal of negotiations. The Indonesian Republic nominated Australia to sit on the committee, which produced the Renville Agreement of January 1948. The Dutch launched a second major military offensive (Operation Crow) and occupied Republican-held territory in Java. Following the Dutch–Indonesian Round Table Conference from August to November 1949, the Republic's sovereignty over Indonesia was officially recognised by the Netherlands in December 1949. The Australian government, led by Robert Menzies, was amongst the first to recognise the new state.
