The Nobel Laureate invited critics to come and see the situation for themselves and said she wanted to speak to Muslims who had stayed and those who had fled to get a better understanding of the crisis. "We want to find out what the real problems are", Suu Kyi said in her State of the Union address.
"We must keep up the pressure on Burma's civilian government to send a clear message to their security forces to stop the violence, ensure a full investigation of allegations of human rights violations, full access to the UN Fact Finding Mission and commit to ensuring accountability for the perpetrators", he said. "And we have to make sure these allegations are based on solid evidence before we take action".
Suu Kyi, in her state address, had stressed on the short time her government has been in power for, adding, "I am aware of the fact the world attention is focussed on the situation in the Rakhine State as a responsible member of the community of nations. At times, her speech amounted to little more than a mix of untruths and victim blaming".
Mr Johnson had earlier joined representatives of the US, Bangladesh, Indonesia, Turkey, Australia, Canada, Sweden and Denmark to raise the issue with Burma's national security adviser on the margins of the United Nations General Assembly in NY.
Over the past month, Nobel Peace Prize Laureate Suu Kyi has come in for widespread worldwide criticism for not speaking out more forcefully as more than 400,000 Rohingya Muslims escaped the Buddhist-majority country into Bangladesh.
United Nations human rights investigators yesterday said they needed "full and unfettered" access to Myanmar to investigate a grave and ongoing crisis, but the government renewed its rejection of the probe.
Many thousands of Rohingya have fled to Bangladesh after a crackdown on militants. On Monday, Chinese Foreign Minister Wang Yi told UN Secretary-General António Guterres that Beijing was supportive of Myanmar's efforts to restore order in Rakhine State and extinguish the "fire of war" there.
The proposals included an immediate end to violence against Rohingya Muslims, creation of "safe zones" in Myanmar for them and urgent humanitarian assistance for the refugees from OIC countries until they can return to Myanmar.
The U.S.is increasing its humanitarian aid to help Rohingya Muslims fleeing Myanmar for neighbouring Bangladesh with 32 million dollars, the State Department said on Wednesday.
She has stayed away from the United Nations meeting of world leaders.
