The Myanmarese people had crossed over to Mizoram in November last year, following clashes between the Myanmar Army and the Arakan Army (AA) militants in the Chin state of that country.
Thanhawla said he had appealed to the Centre to provide assistance to the refugees, staying in three relief camps in southern Mizoram's Lawngtlai district since November 25.
He added that his government was making efforts to ensure that all the refugees returned to Myanmar.
While some of them were afraid of going back apprehending that a violent confrontation might erupt anytime between the government forces and militants, many preferred to settle down in Mizoram, they added.

The refugees, mostly Buddhists and Christians, were residents of Paletwa and surrounding villages in Myanmar.
After fleeing from home, they took shelter in Lawngtlai district's Laitlang, Zochachhuah, Hmangbuchhuah and Dumzautlang villages.
After stray bullets from Myanmar hit a house in Laitlang just ahead of Christmas, the refugees staying there were shifted to the other three villages, an official said.
