In 1904 the French and the British put aside their differences with the Entente Cordiale, which ended their dispute over routes in southern Asia and also removed the Siamese option for using one colonial power as military protection against another. Meanwhile, the Anglo-Siamese Treaty of 1909 produced a compromise, largely in Britain's favour, between Britain and Siam over the disputed territories in the north of Malaya. Siam's next conflict was its two-year involvement in the First World War, fighting on the side of the Entente Powers, the only independent Asian nation with land forces in Europe during the Great War. The result of this intervention in 1917 was the revision or complete cancellation of some of the unequal trade treaties with the United States, France, and the British Empire – but not the return of the bulk of the disputed Siamese territories lost in the previous century.
