(3) Soviet Denunciation of Pact With Japan

(The Department of State Bulletin, Vol. XII, No. 305, April 29, 1945)

The American Ambassador at Moscow transmitted to the Secretary of State, by a telegram dated April 5, 1945, the following statement, as received from the press section of the Foreign Office, regarding Soviet denunciation of the U.S.S.R.-Japanese neutrality pact:

" 'Today at 3 p.m. People's Commissar for Foreign Affairs of the USSR Mr. V. M. Molotov, received the Japanese Ambassador, Mr. N. Sato, and made the following statement to him in the name of the Soviet Government:

" 'The neutrality pact between the Soviet Union and Japan was concluded on April 13, 1941, that is, before the attack of Germany on the USSR and before the outbreak of war between Japan on the one hand and England and the United States on the other. Since that time the situation has been basically altered. Germany has attacked the USSR, and Japan, ally of Germany, is aiding the latter in its war against the USSR. Furthermore Japan is waging a war with the USA and England, which are allies of the Soviet Union.

" 'In these circumstances the neutrality pact between Japan and the USSR has lost its sense, and the prolongation of that pact has become impossible.

" 'On the strength of the above and in accordance with Article Three of the above mentioned pact, which envisaged the right of denunciation one year before the lapse of the five year period of operation of the pact, the Soviet Government hereby makes know to the Government of Japan its wish to denounce the pact of April 13, 1941.'

" 'The Japanese Ambassador Mr. N. Sato, promised to inform the Japanese Government of the statement of the Soviet Government."

(4) Soviet War Declaration on Japan

London, Aug., 8, 1945 - Foreign Commissar Molotoff's (sic) announcement of the declaration of war, as broadcast by Moscow, follows:

On Aug. 8, People's Commissar for Foreign Affairs of the U.S.S.R. Molotoff received the Japanese Ambassador, Mr. Sato, and gave him, on behalf of the Soviet Government, the following for transmission to the Japanese Government:

"After the defeat and capitulation of Hitlerite Germany, Japan became the only great power that still stood for the continuation of the war.

"The demand of the three powers, the United States, Great Britain and China, on July 26 for the unconditional surrender of the Japanese armed forces was rejected by Japan, and thus the proposal of the Japanese Government to the Soviet Union on mediation in the war in the Far East loses all basis.

"Taking into consideration the refusal of Japan to capitulate, the Allies submitted to the Soviet Government a proposal to join the war against Japanese aggression and thus shorten the duration of the war, reduce the number of victims and facilitate the speedy restoration of universal peace.

"Loyal to its Allied duty, the Soviet Government has accepted the proposals of the Allies and has joined in the declaration of the Allied powers of July 26.

"The Soviet Government considers that this policy is the only means able to bring peace nearer, free the people from further sacrifice and suffering and give the Japanese people the possibility of avoiding the dangers and destruction suffered by Germany after her refusal to capitulate unconditionally.

"In view of the above, the Soviet Government declares that from tomorrow, that is from Aug. 9, the Soviet Government will consider itself to be at war with Japan."
