UN High Commissioner for Human Rights Michelle Bachelet arrived in Bangladesh on Sunday for a four-day visit during which she is due to visit the Rohingya refugee camps.
Nearly a million of this Muslim minority in Burma live in miserable conditions in these camps, after fleeing military persecution in their Buddhist-majority country in 2017.
Arriving in Dacca on Sunday, the rights defender, former president of Chile, is due to go to the Rohingya camps on Monday.
Last month, the UN's highest legal body ruled in a landmark case that Burma was guilty of genocide against this minority.
Rohingya refugees refuse to return to their country without guarantees from the military junta to ensure their safety.
And Bangladesh's impatience with the situation is mounting.
Bangladesh has been criticized for its own human rights record under the government of Prime Minister Sheikh Hasina, whom Michelle Bachelet is due to meet during her visit.
Nine groups, including Human Rights Watch, said she should "
publicly call for an immediate end to grave abuses, including extrajudicial killings, torture and enforced disappearances
" in Bangladesh.
Under Sheikh Hasina, security forces have killed thousands in shootouts, while hundreds more, mostly from the opposition, have gone missing, activists say.
The government denies the allegations and, ahead of Michelle Bachelet's visit, it said it would highlight its "
sincere efforts to protect and promote the human rights of the population
".
"
Bangladesh very much hopes that the UN human rights chief will be able to see for herself that the country is working miracles to maintain the course of its development, by integrating human rights
", insisted Dhaka.
