The Ambassador in Japan (Grew) to the Secretary of State
[Received April 25—10:25 a.m.]
602. The following information has been obtained from a reliable source:
The Black Dragon Society, which is both anti-Fascist and anti-Communist, sent a delegation to call on Mr. Matsuoka immediately after his return to Tokyo from Moscow and put to him a series of interrogatories with regard to the extent of the agreement which he had concluded at Moscow. Mr. Matsuoka gave the most categorical assurances that the Japanese-Soviet neutrality treaty contained no secret clauses, that the complete text of all documents signed or agreed upon had been published, and that no oral engagement of any kind was given either by Japan or the Soviet Union. He added that the question of the signatories reducing their respective military forces in [Manchuria?] and in Siberia had not even been discussed.
Repeated to Moscow.
