Article 3 of the treaty left the Bonin Islands and the Ryukyu Islands, which included Okinawa and the Amami, Miyako and Yaeyama Islands groups, under a potential U.S. trusteeship. While the treaty suggested that these territories would become U.S. trusteeship, at the end that option was not pursued. The Amami Islands were eventually restored to Japan on 25 December 1953, as well as the Bonin Islands on 5 April 1968. Both the People's Republic of China (PRC) and the Republic of China (ROC) argue that this agreement did not determine the ultimate sovereignty of the Senkaku Islands.
