Yangon - Veteran U.S. diplomat Bill Richardson was pursuing "his own agenda" and was asked to step down from Myanmar's international advisory board on the Rohingya crisis, a statement from the government said on Thursday.

Richardson said in an interview with Reuters on Wednesday that he was resigning from the board because it was conducting a "whitewash" and accused Myanmar's leader, Aung San Suu Kyi, of lacking "moral leadership".

The departure of Richardson, a former Clinton administration cabinet member, came as the 10-member advisory board was making its first visit to western Rakhine State, from where around 688,000 Rohingya Muslims have fled in recent months.

Thursday's statement from Suu Kyi's office said it became evident in discussions on Jan. 22 that Richardson's intent was not to provide advice "but to pursue his own agenda".

"In view of the difference of opinion that developed, the government decided that his continued participation on the board would not be in the best interest of all concerned," the statement added.

A separate statement from the nine remaining members of the advisory board on Thursday said they met this week "with open minds" and agreed "to speak with one voice".

"Therefore, any statement about the Advisory Board 'whitewashing' or 'cheerleading' for anyone lacks complete legitimacy," it said.

The board was informed that Richardson "had to be asked to leave", it said.

Former South African Defence Minister Roelof Petrus Meyer, one of the four remaining international members of the board, said Richardson's departure was "really unfortunate".

After touring temporary repatriation camps set up by Myanmar, Meyer said he thought the country was ready to take back the Rohingya refugees under an agreement with Bangladesh, where they are currently sheltering.

"The security will be provided...the subject is so internationally covered so I don't think people should be scared," he said.

ARGUMENT WITH SUU KYI

Richardson said in the interview that he got into an argument with Suu Kyi during a meeting on Monday, when he brought up the case of two Reuters reporters who are on trial accused of breaching the country's Officials Secrets Act.

He said Suu Kyi's response was "furious", saying the case of the reporters "was not part of the work of the advisory board". The argument continued at a dinner later that evening, the former New Mexico governor said.

Richardson accused Suu Kyi, a Nobel Peace Prize laureate, of lacking "moral leadership" for declining to speak out against the Myanmar military's campaign in northern Rakhine.

The armed forces have been accused by Rohingya witnesses and human rights activists of carrying out killings, rapes and arson in a campaign senior officials in the United Nations and United States have described as ethnic cleansing. Myanmar rejects that label and has denied nearly all the allegations.

Reporters Wa Lone, 31, and Kyaw Soe Oo, 27, had worked on Reuters coverage of the crisis in Rakhine. They were detained on Dec. 12 after they had been invited to meet police officers over dinner in Yangon.

The Advisory Board for the Committee for Implementation of the Recommendations on Rakhine State was set up by Myanmar last year, to advise on enacting the findings of an earlier commission headed by former U.N. Secretary-General Kofi Annan.

Thursday's statement from Suu Kyi's office said the government was committed to "implementing the recommendations of the Advisory Commission on Rakhine State to the fullest extent possible and in the shortest timeframe, in accordance with the situation on the ground".

In its own statement, the advisory board said it was recommending that U.N. agencies, including the UNHCR, should be invited to take part in the return and resettlement of the Rohingya refugees from Bangladesh.

In an apparent reference to the military's counter-insurgency campaign, launched after Rohingya militant attacks on Aug. 25, the statement called for an "independent fact-finding commission" to look into "the situation in Rakhine state after August 2017".

The commission statement also calls for "wider media access to all affected areas in Rakhine State".
