The United Nations Refugee Agency said that in Myanmar, as of last week, approximately 60,700 women, children, and men have been internally displaced.
Close to 50,000 people are estimated to have been displaced by fighting in Karen areas since the beginning of the year.
The coup sparked protests and other acts of civil disobedience, leading to the deaths of hundreds in military crackdown.
The state government has been taking all humanitarian steps to treat the injured Myanmarese nationals, says the new circular.
Official sources said 15 people including cops had arrived in Mizoram from Myanmar over the past few days.
Reports suggest 19 of them are policemen. The reason behind the migration of the people was not known.
The government has said the arrangement is good for the refugees and the island is designed to offer better living conditions.
