A new Mexican government under President Álvaro Obregón sought recognition, but the Wilson administration refused. Under Harding, both Hughes and Secretary of the Interior Fall opposed recognition; Hughes instead sent a draft treaty to the Mexicans in May 1921, which included pledges to reimburse Americans for losses in Mexico since the 1910 revolution there. Obregón was unwilling to sign a treaty before being recognized, and he and worked to improve the relationship between American businesses and Mexico, reaching agreement with creditors and mounting a public relations campaign in the United States. This had its effect, and by mid-1922, Fall was less influential than he had been, lessening the resistance to recognition. The two presidents appointed commissioners to reach a deal, and the U.S. recognized the Obregón government on August 31, 1923, just under a month after Harding's death, substantially on the terms proffered by Mexico.
