The Secretary of State to the Chargé in Siam (Williams)
16. Your despatch 149 September 30.
If your information is confirmed you may state orally to the Siamese Government that the Government of the United States would be seriously concerned over any action which might have the effect of denying equality of opportunity to American citizens in Siam. An exclusive petroleum or other exclusive concession would have such an effect. While this Government neither gave nor received any assurances in connection with the appointment of an American geological expert, it would obviously not be fair to him or profitable to the Siamese Government to subordinate him to any but Siamese authorities. This Government does not admit that its citizens can justly be excluded from concessions for petroleum development because of any assurances or privileges given to other Governments regarding political cooperation, coaling stations, railways, military or naval matters, etc. Keep Department fully informed by mail, using telegraph only in emergency.
