The boundary of Manipur and Burma (Myanmar) was laid down by an agreement signed between the British authorities (East India Company) and Burma on 9 January 1834 on the river bank of Nighthee (Chindwin). Article No.4 (iii) of this agreement relates to the Tangkhul country. "Fourth (iii) - On the north, the line of boundary will begin at the foot of the same hills at the northern extremity of the Kabo Valley and pass due north up to the first range of hills, east of that upon which stand the villages of Chortor (Choithar), Noongbee (Nungbi), Nonghar (Nunghar), of the tribe called by the Munepooriis (Manipuris) as Loohooppa (Tangkhul), and by the Burmahs Lagwensoung, now tributary of Manipoor." As a result of this boundary demarcation without the knowledge let alone consent of the Tangkhuls, many Tangkhul village situated in Somrah hills are included under Burma. Later, when India and Burma attained national independence, the Tangkhuls found themselves totally dismembered belonging to two different countries.
