The Secretary of State to the Chargé in Mexico (Summerlin)
110. For Warren and Payne.
Department deems it important that it should inform the Governments of Belgium, Great Britain, France and Cuba through their missions in Washington as to the results of your negotiations, as well as any action which the Government of the United States may plan to take because of the same, prior to any official announcement regarding the result of your negotiations including the provisions of the claims conventions. It is evident of course that such information cannot be supplied until you have brought the details to Washington.
It is the desire of the Department that you be guided by the above in all statements made public by you through newspapers or otherwise relative to your negotiations.
Likewise you will advise the Commissioners of Mexico that no public statement relative to the details of the negotiations will be made by you until you have returned to Washington and consulted with the Department.
