THE UNITED STATES is prepared to place under trusteeship, with the United States as the administering authority, the Japanese Mandated Islands and any Japanese Islands for which it assumes responsibilities as a result of the Second World War. Insofar as the Japanese Mandated Islands are concerned, this Government is transmitting for information to the other members of the Security Council (Australia, Brazil, China, Egypt, France, Mexico, the Netherlands, Poland, the Union of Soviet Socialist Republics and the United Kingdom) and to New Zealand and the Philippines a draft of a strategic area trusteeship agreement which sets forth the terms upon which this Government is prepared to place those islands under trusteeship. At an early date we plan to submit this draft agreement formally to the Security Council for its approval.
Note: The text of the draft agreement is published in the Department of State Bulletin (vol. 15, p. 889).
