The Bangladesh delegation comprising Home Secretary Md Abdul Karim, Bangladesh Rifles director general, director general for South Asia at the foreign ministry, and Additional Inspector General of Police, among others, left Dhaka yesterday for the 8th version of the talks.

Both sides are also likely to take advantage of recent friendliness between Dhaka and New Delhi to re-energise deals on joint-border patrolling and border demarcation issues.

The two sides will follow up an announcement made through a joint statement during Indian Foreign Secretary Shivshankar Menon's Dhaka visit in June on sharing sensitive security 'information' between the two countries.

Degree and nature of such an arrangement will be discussed during the talks, foreign ministry sources said.

Both the sides are also likely to share intelligence on 'cross-border crimes' in line with the commitment to 'enhance security cooperation', sources added.

Dhaka will also look to raise a number of old irritants such as implementation of the 1974 land agreement, border fencing by India, alleged 'push-in' of Bangla-speaking Indian nationals, cross-border smuggling and continuing firefights between the BDR and India's Border Security Force (BSF).

The meeting is likely to iron out differences regarding the Dhaka-Kolkata train service, which has been delayed due to Indian reservations about security arrangements at the border and in Bangladesh territory.

Bangladesh shares 4,200 km common border with India, which is the longest border shared by either of the countries with another neighbour.

Only 6.5 kilometres remain unresolved along the common border. There are 92 Bangladeshi enclaves on the Indian side while 106 Indian enclaves are in Bangladesh territory.
