Dhaka, July 20 - Bangladesh has said that if the parliamentary team visiting the site of an Indian dam finds it 'harmful', it would demand a meeting of the Joint Rivers Commission (JRC), to be attended by the prime ministers of the two countries.

JRC is the official forum at which the two countries discuss issues relating to rivers.

Bangladesh Water Resources Minister Ramesh Chandra Sen told a seminar Sunday that should there be anything to indicate negative impact of the dam India proposes to build on the Barak river at Tipaimukh in Manipur, the JRC would need to be attended by prime ministers Sheikh Hasina and Manmohan Singh.

His assurance came amidst rising protests here against the Indian project as main opposition Bangladesh Nationalist Party (BNP) has joined a section of environmentalists and NGOs who allege that the dam would deny Bangladesh its share of water and adversely impact the environment in the northeastern Sylhet region.

The two prime ministers met in Egypt last week when Manmohan Singh assured that India would not 'do nothing' that would hurt Bangladesh's interests.

This assurance itself has added to the rival demands as the issue gets politicised and tempers among the protesters are running high, political analysts said.

BNP chief and two-term prime minister Khaleda Zia asked India to abandon the project, while Hasina Saturday called for 'national unity' to be able to 'bargain better' with India.

India mooted in May that Bangladesh send a team to visit the proposed dam's site. The formation of the team of parliamentarians has also become controversial with the BNP withholding nomination of its two lawmakers on the team till 'neutral' water resource experts are included.

Sen again asked the BNP to give the names for the team that will be headed by Abdur Razzak, a former minister who is the chairman of parliament's standing committee on water resources.

The delegation will leave Dhaka July 29 to make a preliminary assessment of the impacts the proposed dam may have on Bangladesh.
