evidence: It is a fact, from 15th century Kabaw Valley was in the possession of Manipur till 1834 except for some periodical occupation by Burmese now and then, which the Manipuri King destroyed by war and established the legitimate right and at the same time right by conquest. James Johnstone has stated that Manipur held a considerable territory east of the Chindwin River in subjection, at other times only the Kabaw Valley, a strip of land, inhabited not by Burmese, but by Shans, and lying between Manipur proper and the Chindwin. [...] Kabaw Valley is still a question which touches the sentiment of the people of Manipur. During the Third Burmese war in 1885 the British forces invaded Upper Burma through Manipur and Kabaw Valley. And Kabaw Valley became a possession of the British. The King and Ministers of Manipur wanted the retrocession of Kabaw Valley which did not take place. [...] It is said that the interest of the Defence Ministry was aroused at the hint that if Kabaw Valley were reverted the Chindwin could be a good defence boundary, but diplomatic considerations led to the dropping of the Kabaw Valley topic. [Gangmumei Kabui 1988:35-36] Thus, Manipur lost her old territory, the Kabaw Valley. The present boundary of Manipur with an area of 22327 sq. kms remained fixed since the controversial transferred of Kabaw Valley to Burma in 1834. [Gangmumei Kabui 1991:7] But the boundary problem between Manipur (India) and Myanmar (Burma) still remains unsolved.
