Philippine President Rodrigo Duterte made another seemingly off-the-cuff remark when he told Myanmar leader Aung San Suu Kyi that she shouldn't worry about Human rights activists as they are "just a noisy bunch".
Richardson, a former governor of the US state of New Mexico and former US Ambassador to the United Nations, was one of five members who agreed to join the Advisory Board on the Implementation of Recommendations on Rakhine State previous year.
An advisory board chaired by former Thai foreign minister Surakiart Sathirathai has lashed out at the recent resignation of USA member Bill Richardson, saying his accusation that the board was "whitewashing" or "cheerleading" Aung San Suu Kyi over the Rohingya crisis completely lacked legitimacy.
His remarks come as Suu Kyi has faced mounting global criticism as Myanmar to seek refuge in neighboring Bangladesh.
The advisory board met with State Counselor Aung San Suu Kyi on Monday and discussed a work plan on the repatriation of displaced people from Bangladesh fleeing Rakhine conflict.
They are President Joko Widodo of Indonesia, Philippines President Rodrigo Duterte, Prime Minister Lee Hsien Loong of Singapore, Prime Minister Thongloun Sisoulith of Laos, Prime Minister Nguyen Xuan Phuc of Vietnam, Prime Minister Najib Razak of Malaysia, Prime Minister Hun Sen of Cambodia, General Prayuth Chan-o-cha of Thailand, Aung San Suu Kyi of Myanmar and Sultan of Brunei Haji Hassanal Bolkiah. "Among the circus of commissions over many years, the Annan commission was a rare exception" in that it produced actionable suggestions and criticism of government policies, he said.More news: IPL Auction : Day 1 round up - Ben Stokes fetches highest bid
The vast Kutupalong camp shelters numerous 688,000 Rohingya refugees who have fled across the border from Myanmar's Rakhine State following an outbreak of violence there in late August a year ago. He said he had informed the US Ambassador in Yangon and the State Department of his intention to resign but did not seek their guidance or permission to do so.
Suu Kyi is facing worldwide criticism for failing to address the plight of the Rohingya, more than 688,000 of whom have fled to Bangladesh to escape a crackdown by the Tatmadaw army of Burma. Inside Myanmar the Rohingya are widely regarded as illegal immigrants from Bangladesh even though many have lived there for generations.
"It appears that the Board is likely to become a cheerleading squad for government policy as opposed to proposing genuine policy changes that are desperately needed to assure peace, stability, and development in Rakhine State". He accused Aung San Suu Kyi of lacking the sincerity and moral leadership to tackle the crisis.
"And she exploded", he said on Friday.
The intense worldwide criticism of the government's handling of the Rohingya crisis has in turn created something of a siege mentality in Myanmar.
