The Secretary of State to the Ambassador in Argentina (Armour)

Washington, July 10, 1943—8 p.m.

1010. Your 1481, July 3, 1943. The British Government is about to place an embargo on all cipher telegrams filed by Axis missions with [Page 529] telegraph companies under British control for transmission by cable. The British have asked us whether we will take similar action with regard to United States companies.

Before taking similar action with regard to the I. T. & T. cable from Buenos Aires to Rio de Janeiro, the Department wishes your views with regard to possible reactions in Argentina.

The Department is instructing the Embassy in Rio to ascertain whether the Brazilian authorities will be willing to forbid the transmission of all messages in code over its international radio circuits.
