Assam-Mizoram Border Issues 

• Recently, residents of Assam and Mizoram have clashed with each other over conflicting territorial claims that have persisted for long since the formation of Mizoram as a separate state in 1987.

•  Assam and Mizoram share a 164.6 km inter-state border.

• The dispute stems from a notification of 1875 that differentiated Lushai Hills from the plains of Cachar, and another of 1933 that demarcates a boundary between Lushai Hills and Manipur.

• According to an agreement between the governments of Assam and Mizoram, status quo should be maintained in no-man’s land in the border area. However, clashes have erupted from time to time over the issue.
