The Chairman said he was disappointed with Myanmar de facto leader Aung San Suu Kyi's conduct regarding the crisis as she was awarded the European Parliament's Sakharov Prize for human rights in 1990 and is a Nobel peace laureate.
The current crisis erupted on August 25, 2017 following an attack by a Rohingya insurgent group that led to a violent response by the Myanmar Army in the state of Rakhine, where it is calculated that around one million Rohingyas lived.
