Tokyo, the 11th March, 1941.
Monsieur le Ministre,
By the letter under today's date, Your Excellency was good enough to inform me as follows :
[text of the Japanese letter]
I have the honour to acknowledge the receipt of the above letter and to inform Your Excellency that the Government of Thailand are disposed, under the present situation, to accede to the instance of the Japanese Government, although they are not obliged to do so either from the standpoint of the local situation or from that of the fortune of arms. The Government of Thailand, being constantly solicitous of the maintenance of peace of Greater East Asia, have never taken initiative of such a nature as of disturbing that peace, but testify to their fidelity to the basic spirit which inspired the treaty of June 12, 1940, by accepting the Mediation Plan presented on separate sheet. On the basis of that spirit and being desirous of avoiding all kinds of engagement which will involve their country in a conflict between third Powers, the Government of Thailand hereby declare that they have no intention of entering into any agreement or understanding with a third Power or Powers envisaging political, economic or military cooperation aimed either directly or indirectly against Japan. Moreover, it is expected by the Government of Thailand that the Government of Japan will assure the strict observance of the treaty of the 12th of June, 1940.
I avail myself of this opportunity to renew to Your Excellency the assurance of my highest consideration.
