Indonesia gained independence from the Dutch Empire in 1949 after the latter failed to restore colonial control. As mentioned above, Indonesia also wanted a powerful position in the region that could be lessened by the creation of united Malaysia. The Netherlands retained its New Guinea part from the previous Dutch East Indies, but Indonesia threatened to invade and annex it. A vote was supposedly taken under the UN sponsored Act of Free Choice to allow West New Guineans to decide their fate, although many dispute its veracity. Later, Portugal relinquished control over East Timor in 1975, at which time Indonesia promptly invaded and annexed it.
