The most accurate response comparing the situation of Indigenous ethnic minorities in Myanmar and Cambodia is:
"Many Indigenous ethnic minorities in Myanmar are oppressed by the government and have fled the country, but today Cambodia has a policy of tolerance toward Indigenous ethnic minorities."
In Myanmar, ethnic minorities, particularly in conflict areas, have faced significant oppression, violence, and forced displacement, often leading to a refugee crisis. In contrast, Cambodia has made some efforts to show tolerance and support for its Indigenous populations, although challenges remain in terms of rights and recognition.
