The Terai lands, however, proved difficult for the British to govern and some of them were returned to the kingdom later in 1816 and the annual payments accordingly abolished. However even after the conclusion of the Anglo-Nepalese War, the border issue between the two states was not yet settled. The boundary between Nepal and Oudh was not finally adjusted until 1830; and that between Nepal and the British territories remained as a matter of discussion between the two Governments for several years later.
