The document, an Optional Form number ten, is a United States Government Memorandum addressed to Mr. John A. Armitage, from Charles C. Flowerree of INR:RSB, dated November twenty-fifth, nineteen-sixty. The subject is "Warsaw Report on ChiCom Nuclear Weapons Activities." In reference to Warsaw's seven hundred ninety-one of November twenty-first, the following information could be conveyed to appropriate foreign diplomatic personnel in Warsaw: "It is true that the Chinese Communists have built three atomic reactors.

This assistance has been considerable in the past, but there is good reason to believe that the current political dissensions have caused a severe cut back in Soviet aid which could stall the Chinese nuclear weapons program for some time. There is little doubt, however, that the Chinese have attained a competence in atomic energy which would enable them eventually to produce a weapon of their own, even with no further Soviet assistance." Regarding an alleged atomic explosion in the Gobi desert region, the memorandum states: "to date intelligence has received no evidence which would lead to the conclusion that an atomic explosion has occurred anywhere in…
