Jabarkan Ellsworth Bunker proposal dari Ma'ruf Amin dalam bahasa jawa

Facing mounting international diplomatic pressure and the prospect of an Indonesian invasion force, the Dutch conceded to re-entering negotiations and agreed to the Ellsworth Bunker proposal on 28 July 1962, for a staged transition from Dutch to Indonesian control via UN administration, on the condition that a plebiscite would be held in future in the territory.[11] The agreement was signed on 15 August 1962 at the UN Headquarters in New York and the territory was placed under the United Nations Temporary Executive Authority in October 1962. It was subsequently transferred to Indonesia in May 1963.

The territory formally became part of Indonesia in 1969 after the Indonesian government, who shifted to New Order under President Suharto starting from 1966, conducted a Bunker proposal-based plebiscite termed the Act of Free Choice. The result, which under strong pressure from the military, unanimously wanted to become part of Indonesia. The UN General Assembly later accepted the result via the UN Resolution 2504. This act has been criticised by some in the international community, including the group International Parliamentarians for West Papua, which has termed the act "the act of no choice".
