83 years later, a new treaty now known as the Anglo-Siamese Treaty of 1909 or the Bangkok Treaty of 1909 was signed between the two powers. In the new agreement, Siam agreed to give up its claim over Kedah, Perlis, Terengganu and Kelantan, while Pattani remained Siamese territory. Perlis was previously part of Kedah but during the Siamese reign it was separated from Kedah. Kedah's district of Satun however was annexed by Siam in the same agreement. Pattani on the other hand was dissected into Pattani proper, Yala and Narathiwat after the signing of the treaty.
