Mizoram has claimed a 509 square miles area of inner line reserved forest notified under the BEFR as its actual boundary since a long time back.
Assam on the other hand, claimed that the boundary as per a survey of India’s map in 1933 is its constitutional boundary.
Lalchamliana also said that the next round of border talks with Assam is yet to be decided.
Mizoram and Assam have held 3 rounds of ministerial-level talks to resolve the long pending inter-state border dispute.
Besides, the two neighbouring states have also held virtual meetings on several occasions
Three districts of Mizoram- Aizawl, Kolasib and Mamit districts share a 164.6 km long inter-state border with three Assam districts- Cachar, Hailakandi and Karimganj.
The border dispute between the two Northeastern states is a long pending issue, which remains unresolved till today.
The firing between police forces of the two states will turn 2 years on July 26.
In the firing that occurred on July 26, 2021, 7 people, including 6 policemen from Assam were killed and around 60 people from both the states were injured.
Following the incident, the two neighbouring states began high-level delegation talks from August 2021 to resolve the vexed border dispute.
In the last border talks held in Guwahati in November last year, both delegations had decided that Mizoram will furnish the list of villages, their areas, geospatial extent, and ethnicity of the people and other relevant information within three months to support its claim which can be examined by setting up regional committees from both sides to arrive at an amicable resolution to the vexed border issues.
In January, the Mizoram government formed a study group and submitted its claim the next month.
Mizoram Chief Minister Zoramthanga and his Assam counterpart Himanta Biswa Sarma had also met twice in New Delhi in November 2021 and September last year to find an amicable solution to the border dispute.
