(MEMORANDUM)

During the current negotiations between representatives of the United States and the Japanese Governments looking to the conclusion of the Agreement for Cooperation between the Government of the United States and the Government of Japan concerning Civil Uses of Atomic Energy, the representatives of Japan have requested that the United Stales Government clarify its position with respect to the purchase option provision of Article VII F of the proposed. Agreement.

Article VII F (a) of the the proposed Agreement reserves to the United States Government the option to purchase from Japan special nuclear material which is produced in reactors fueled with material obtained from the United States in excess of the needs of Japan's program for the peaceful uses of atomic energy. The United States Government has proposed the inclusion of this provision in full awareness of the significance of the president's statement of November 18, 1956, which reads in pertinent part as follows:

"One of the steps I have approved is an offer to purchase at specified prices plutonium and uranium 233 produced in reactors abroad that are fueled with material furnished under our agreements for cooperation. The materials so acquired by the United States will be used solely for peaceful purposes." This statement has not since been revoked or modified and continues, therefore, to be the policy of the Unied States in this matter, It is hoped that the foregoing clarifies the United States Government's position with respect to Article VII F (a).

Department of State,

Washington.
