Pope Francis left Rome on Sunday night and will become the first pope to visit Myanmar when he arrives Monday.

The world’s most high-profile Christian is about to take center stage in a staunchly Buddhist country accused of horrifying acts of brutality against its Rohingya Muslim minority.

Experts say the key question during the Pope’s visit to Myanmar is how he’ll choose to address the Rohingya crisis.

“This is something he hasn’t shied away from the in the past,” Alistair Cook, coordinator of the Humanitarian Assistance and Disaster Relief Program at the S. Rajaratnam School of International Studies, told CNN.
