The Prince of Wales is to hold a meeting with Nobel peace laureate Aung San Suu Kyi at his official London home.
Ms Suu Kyi, Burma's de facto leader who is in Europe for a series of meetings, will sit down for talks with Charles at Clarence House, the third time the pair have met.
Burma's government is facing international criticism for its activities in the western state of Rakhine.
Troops are accused of widespread abuses against the Muslim ethnic Rohingya minority in what the government says is a counter-insurgency operation.
Ms Suu Kyi has been accused of not speaking out against what has been described as the ethnic cleansing of the Muslim communities.
But she has strongly denied this and in a recent BBC interview said people have claimed she has said nothing on this issue "simply because I didn't make the kind of statements which I should make, which is to condemn one community or the other."
She has close connections with Britain having read philosophy, politics and economics at St Hugh's College, Oxford, between 1964 and 1967, before settling in the university city with her late husband Michael Aris, a Tibetan scholar.
In July 1989, around a year after her return to her homeland to care for her mother, Ms Suu Kyi was placed under house arrest by the military which feared the influence of a woman whose father was instrumental in gaining Burma's freedom from British rule.
She remained there for much of the next 20 years, finally being released in November 2010.
Her husband died of prostate cancer in 1999 at the age of 53. He had asked the Burmese authorities to grant him a visa to visit her one last time, but was refused.
Charles knew Mr Aris and the year the scholar died he became patron of the Michael Aris Memorial Trust for Tibetan and Himalayan Studies.
Despite a landslide victory for Ms Suu Kyi's National League for Democracy party in the 2015 Burmese general election she was barred by the constitution from becoming president as her two children are foreign nationals.
Htin Kyaw was sworn in as president but the Nobel peace laureate has indicated whoever holds the post is her proxy.
