Dhaka: Bangladesh wants its friends, including India, to play a significant role in resolving the Rohingya crisis for maintaining regional stability and security, said Prime Minister's International Affairs Adviser Dr Gowher Rizvi on Tuesday.

"We understand every country's constraints, but their support is very important (to resolve Rohingya crisis). It's not a question of supporting Bangladesh while it's a pure genocide (against Rohingyas)...we do expect our friends to play an important role," he said.

Rizvi came up with the comments while speaking at the inaugural session of Bangladesh-India Security Dialogue: Round-8 jointly arranged by Bangladesh Enterprise Institute and Observer Research Foundation of India at a city hotel.

He said the Rohingya issue needs very special attention and efforts on geopolitical consideration as the crisis is a security threat to the sub-region of Bangladesh Myanmar and India.

"If we don't work on it jointly and strongly together, I fear it may undo some of the good works that have happened over the years in the region. We need to coordinate our action together and we need to realise that it'll remain as a security threat unless we work together," Rizvi said.

He appreciated India for its humanitarian assistance to face the Rohingya crisis saying it has so far been the largest supplier of the relief materials for Rohingyas. "We're grateful for it and we need to acknowledge it."

"I would like also to tell my Bangladeshi friends that everything is not done within the public domain as there're lots more things happenings behind the scene. I think it's very important on our part to understand that every country whether it is China or India or any other one has multiple interests and concerns," he said.

The PM's adviser also said it is not wise to reduce the relationships between the two countries on a single line.

He said it is true that the relationship between Bangladesh and India is now the best that it had ever been and the two countries achieved many things over the last 8-9 years.

Rizvi said Bangladesh and India can resolve any difference of opinion through talks as the two countries have no inherent conflict.

He, however, said the failure to sign the Teesta agreement is a major setback for the relationship of the two countries as it has created a bad public perception and feeling in Bangladesh.

Mentioning that Bangladesh has still high focus on signing the Teesta deal, Rizvi hoped that the two countries will make a good progress on it through talks.

He also voiced disappointment for the slow progress of disbursement of Indian Line of Credit (LoC), saying India needs to address it.

Rizvi focused on regional cooperation and unhindered connectivity among Bangladesh, India, Bhutan and Myanmar as it will work as a driving force to alleviate poverty.

The PM's adviser also said it is now a real challenge for the two neighbouring countries to improve transport connectivity. "Efforts are on to this end at the government level. "But people want to see a greater role of the private sector in this regard."

He also said border killing has significantly gone down in recent days for better border management. "But we have to be mindful about drug and human trafficking."

Pinak Chakravarty, distinguished fellow at the Observer Research Foundation, said the stability and maturity of ties between Bangladesh and India is quite remarkable and it happened mostly in the last decade for outstanding leadership on both sides "We've now more communion better exchanges, breaking down of old mindsets and many other progress in many areas."

But, he said, the two countries need to look again at many more important challenges like water one. "We need to work out how we'll deal with it. I don't like to say water sharing. I prefer to describe it as water management. It's a matter of water management rather than sharing. Because we have access to water during one season and we have less water during other seasons. So, it's our challenge to ensure access of water through better management."

"Maritime time security is a major area for us, particularly in the bay of Bangla, which is emerging as area of competition. Though there's no conflict yet, but there has certainly huge competition. It's where we need to cooperate for the better use of our resources bilaterally and through mechanism of joint exploration and some thing like that," the Indian diplomat observed.

President of Bangladesh Enterprise Institute Farroq Sobhan said Bangladesh is facing a major new challenge of humanitarian crisis as nearly 600,000 Rohingyas entered Bangladesh during the past six weeks. "It has the potential of becoming a major security challenge for both India and Bangladesh."

The diplomat said development of solid bilateral relationship, based on the multifaceted economic, security and political cooperation is necessary for the sake of the peace, stability and prosperity in the region. "A longstanding durable relationship between the two countries is also necessary to promote connectivity."

Mentioning that border management is an issue of great concern for the security and stability of the two countries, he said greater cooperation in this area will pave the way for solving some of the perennial border issues.
