Bangladesh is not in a hurry to relocate Rohingya refugees to a Bay of Bengal island, a minister told Reuters yesterday, after the United Nations sought more details on the government's plan.

Bangladesh wants to move 100,000 of the nearly 1 million Rohingyas sheltered in cramped camps in Cox's Bazar to the remote island, known as Bhasan Char, which it has been developing for the past two years.

The UN is making plans to help Bangladesh with the move, Reuters reported on Saturday.

But in a statement yesterday, the world body called for a thorough assessment to ensure the viability of the move, saying it was discussing “critical protection and operational issues” ahead of any relocation.

“We're also examining the potential operational implications of setting up a humanitarian response on Bhasan Char, including the requirements, time frames and costs involved,” it said.

Bangladesh is in talks with UN humanitarian bodies, and working on their observations, said Enamur Rahman, state minister for disaster management and relief.

“So we are going a little slow. There's no exact date to relocate,” he added.

“We are not in a hurry and it will start only when all these UN bodies and Rohingya people feel the area is ready.”

Enamur said the government was working to build more cyclone shelters on the island, which is hours from the mainland by boat.

Many Rohingyas have opposed the transfer plan.

A World Food Programme document shows the UN's food agency supplied Bangladesh with detailed plans, including a timeline and a budget, on providing for thousands of Rohingya taken to the island within weeks.

The March 12 plans show how the agency and its partners “may facilitate the identification, staging, forward movement, reception, and sustainment of refugees” on the island, based on an initial appeal for donor funds from $9 million to $19 million.

Densely-populated Bangladesh says it has been grappling with the large refugee numbers.

The number of refugees in Cox's Bazar has swelled since August 2017, when a Myanmar military-led crackdown that UN investigators have said was conducted with “genocidal intent” prompted some 730,000 Rohingya to flee.

Buddhist-majority Myanmar has denied almost all accusations of atrocities made by refugees, saying its security forces engaged in a legitimate counterterrorism operation.
