Assam and Meghalaya partially resolved their 50 year old border dispute along their 884.9 km boundary.
Meghalaya carved out of Assam by passing of an act known as Assam Reorganisation ( Meghalaya ) Act , 1969 and became a full- fledge state in 1972.
Meghalaya questioned the reorganisation and claimed that the area of present day East Jaintia Hills , Ri-Bhoi and West Khasi Hills districts of meghalaya who got transferred to Assam by the Act, belongs to their tribal chieftains . After claims and counter -claims , the dispute was narrowed down to 12 sectors as claimed by Meghalaya in 2011.
The first serious attempt to solve the border dispute began in 1983 by forming a joint official committee , which sought the intervention of Survey of India to re-delineate their boundaries . After 1983 , there were various steps taken to solve the dispute but none proved fruitful . In 2019 , the Meghalaya government petitioned Supreme Court to direct centre to settle the dispute.
In January 2021, Home Minister Amit Shah urged all north- eastern states to settle their disputes by August 15, 2022 . As a result , in June 2021 , the two states decided to resume talks at CM level and adopt a 'give and take ' policy .
Of the 12 disputed regions , the less complicated six regions- Tarabari, Hahim , Gizang , Ratacherra , Boklapara and Khanapara- Pilingkata were chosen for the first phase . Both the states formed three regional committees on whose recommendation , the two state governments prepared a draft resolution on January 29 which paved the way for closure of six disputed regions.
