Dhaka, July 28 - Bangladesh will insist on a joint study to determine any adverse impact on its ecology that a dam India proposes to build near its border, a senior politician said Tuesday.

A day before a Bangladesh team's departure for New Delhi, former Water Resource Minister Abdur Razzak was quoted by bdnews24.com as saying that pending such a study, he would seek a assurance that India will not go ahead with the project, nor divert water from the river that is common to both neighbours.

Razzak, who will lead an 11-member team, told the website that as per the minutes of the Joint Rivers Commission (JRC) meetings and a Bangladesh study on the proposed dam, if India solely implements a power project in Tipaimukh, it would not harm Dhaka's interests.

Tipaimukh dam is proposed to be built on Barak river in India's Manipur state.

'Despite the study and the JRC agreements, we will propose carrying out a joint-study to know whether the Tipaimukh dam will cause any harm to Bangladesh,' said Razzaq, who is also the chairman of the parliamentary standing committee on water resources ministry.

He said Bangladesh had been opposing implementation of the irrigation project over Barak river since 1978.

'We will firmly ask the Indian side that they must not implement the irrigation project at Phulertala. Because, irrigation project means water diversion (from the upstream),' he told the website.

The team leaving Dhaka for New Delhi Wednesday will have lawmakers, officials and a water resource expert.
