The treaty between Siam and the French Republic was signed at Bangkok on 23 March 1907 by Prince Devawongse Varoprakar, minister for foreign affairs, and Victor Collin de Plancy, minister plenipotentiary. Two copies, French and Siamese; in case of difficulty the French text governs. Ratifications were exchanged in Paris on 21 June 1907, within the four-month period. It supplements the convention of 13 February 1904. It is not the Anglo-Siamese treaty of 1909, a distinct instrument.

Article I: Siam cedes to France the territories of Battambang, Siem Reap and Sisophon, with the frontiers in the delimitation protocol. Article II: France cedes to Siam Dan Sai and Trat (Kratt), and the islands south of Cape Lemling as far as and including Koh Kut. Article III: delivery within twenty days of ratification. Article IV: a mixed commission within four months, following the protocol. The protocol line is not reproduced here as a gazetteer.

Article V: French Asiatic subjects and protégés registered after signature come under the ordinary Siamese courts; those already registered remain, until the Siamese codes enter into force, under the international courts extended throughout Siam. Article VI: the same rights of property, residence and travel as natives; ordinary taxes; exemption from military service and extraordinary requisitions. Article VII: earlier treaties remain in force so far as not modified.

The delimitation protocol describes the Indochina–Siam frontier from the sea to the Mekong and, at Luang Prabang, along the watershed; the commission may substitute natural lines for conventional ones, without prejudice to Siam. The jurisdiction protocol regulates the international courts, evocation and appeal. Later demarcation maps departed from the text in places — including at the temple of Preah Vihear; that is a later question, not in the 1907 articles.

The exchange reunited Angkor with French colonial Cambodia and closed, between Siam and France, the series of adjustments that followed the 1893 crisis. This is not an occupation handbook.
