SYDNEY — Myanmar’s de facto leader Aung San Suu Kyi on Monday pulled out of a public speech and question-and-answer session in Sydney because she was “not feeling well”, the event’s organizers said.

Suu Kyi has been under fire internationally for her public silence about a military crackdown in Myanmar’s Rakhine state that has seen nearly 700,000 of the Muslim Rohingya minority flee to Bangladesh.

She had been due to make a keynote speech at the Lowy Institute think-tank in Sydney Tuesday.

The speech and subsequent Q and A session would have been the only public comments the Nobel Prize winner would have made during her Australia trip.

“This afternoon the Lowy Institute was informed by the Myanmar embassy that the State Counselor will no longer be able to participate in this event as she is not feeling well,” a spokeswoman for the think-tank said in a statement.

“Accordingly, the event is now cancelled.”

Meanwhile, Suu Kyi arrived in Canberra on Monday to be met by a military honor guard and Australian Prime Minister Malcolm Turnbull, who has said he will raise human rights issues during her visit.

Australia’s Attorney General has said he would not allow the lawsuit, lodged by activist lawyers in Melbourne on behalf of Australia’s Rohingya community, to proceed because Suu Kyi had diplomatic immunity.

Since coming to power in 2016, Suu Kyi, who won the 1991 Nobel Peace Prize for her struggle for democracy in Myanmar, has faced growing criticism for failing to condemn or stop military attacks on her country’s minority Rohingya Muslims.

Neither Suu Kyi nor Turnbull made public remarks before their meeting, but the Australian leader said on Sunday that Suu Kyi spoke “at considerable length” during the ASEAN meeting about Rakhine State, appealing to her Southeast Asian neighbors for humanitarian help.
