A total of 6.1 km of the international border between India and Bangladesh in three sectors -- Daikhata-56 (1.5 km in West Bengal), Belonia (1.6 km in Tripura) and Lathitilla-Dumabari (3 km in Assam) -- remains undemarcated, he told the Rajya Sabha.

The state minister said two Joint Boundary Working Groups were set up to resolve all pending issues relating to the implementation of the Land Boundary Agreement in 2001, which met twice -- in July 2001 and March 2002, according to a press release of the Press Information Bureau of the Ministry of External Affairs posted on a website.

Replying to a question, the state minister said that during the second meeting of the Joint Boundary working Group in New Delhi, India had offered a composite package to Bangladesh for the demarcation of the pending segments of the international boundary.

The government of India is awaiting a response from the Bangladesh, he added.

The issue was also discussed in the Foreign Office consultations held in June when the two sides agreed to continue discussions to expedite the completion of the demarcation of the land boundary.

It was decided to resume meetings of the Joint Boundary Working Groups (JBWG) to consider the boundary-related issues, he added.
