Pope Francis arrived in Bangladesh on Thursday, where hundreds of thousands of Muslim Rohingya refugees have sought sanctuary after fleeing a crackdown in neighbouring Myanmar.
The pope will spend three days in mainly-Muslim Bangladesh - the second stop on his tour dominated by the plight of the persecuted minority.
In Myanmar he walked a diplomatic tight-rope, staying away from allegations that the army is waging an ethnic cleansing campaign against Rohingya Muslims, despite pressure to confront the incendiary issue publically.
He also refrained from mentioning the Rohingya by name during his four-day trip in which he held two masses and private meetings with civilian leader Aung San Suu Kyi and powerful army chief Min Aung Hlaing.
In Dhaka he will meet some of the refugees from the Rohingya community, whom he has described as his "brothers and sisters", and led a mass for Bangladesh's tiny Catholic minority.
Nearly a million refugees now languish in camps on the border and the Daily Star, a Bangladeshi newspaper, said in an editorial Thursday it hoped he could change their fate.
"Thanks to the large body of evidence documenting severe rights abuses of the Rohingya minority of Myanmar, the extent of the atrocities carried out by Myanmar's security forces is known to all," it said.
"We remain hopeful that given Pope Francis' legacy of standing up for the oppressed, he will speak out against the ongoing persecution of the Rohingya during this very important visit."
Myanmar's government denies the Rohingya are an ethnic group, insisting they are "Bengali" immigrants who are not entitled to full citizenship.
The Vatican has rejected suggestions that the pope's reticence to tackle the Rohingya crisis head-on represented a failure of moral leadership.
A spokesman said the pope's presence alone drew attention to Myanmar's myriad troubles and his "moral authority" remained undimmed.
"He's not afraid of minefields," Vatican spokesman Greg Burke said on Wednesday, hinting the pope's discussions in private may have been more strident.
Francis had been urged not to utter the Rohingyas' name in Myanmar to avoid provoking hard-line Buddhists and making the country's Catholic community a target.
"He seemed to comprehend the dilemma he faced," David Mathieson, a Yangon-based analyst, said, applauding his diplomatic dexterity in a country where the army still holds great power.
"He is the Pope, not a pugilist ... he was here to help the country work through this horrific humanitarian crisis and listen to both the civilian and military leadership."
Pope in Myanmar
The pontiff was warmly embraced by Myanmar's Catholics, who make up just over one per cent of the population.
On Friday he will lead a mass in central Dhaka that is expected to be attended by around 100,000 Bangladeshi Catholics.
The country's Catholic community accounts for less than 0.5 per cent of the population of 160 million and have for centuries lived in relative harmony with their Muslim neighbours.
But the country has seen a rise in Islamist attacks in recent years targeting religious minorities, foreigners and secular figures.
Pope Francis's visit coincides with the disappearance of a Catholic priest on Monday in the same village where suspected Islamist extremists hacked a Catholic grocer to death last year.
Walter William Rosario, 40, had been making arrangements for some 300 Catholics to travel to Dhaka for the pope's mass.
Since 2015 at least three Christians, including two converts from Islam, have been hacked to death in attacks blamed on militants.
