In the 1930s, Siam engaged France in a series of talks concerning the repatriation of Siamese provinces held by the French. In 1938, under the Front Populaire administration in Paris, France had agreed to repatriate Angkor Wat, Angkor Thom, Siem Reap, Siem Pang and the associated provinces (approximately 13) to Siam. Meanwhile, Siam took over control of those areas, in anticipation of the upcoming treaty. Signatories from each country were dispatched to Tokyo to sign the treaty repatriating the lost provinces.
