(AFP) -- "We believe it would be very important to have UNHCR fully involved in the operation to guarantee that the operation abides by international standards," Guterres told a press conference at UN headquarters.

The agreement, finalized in Myanmar's capital Naypyidaw this week, sets a two-year deadline for the repatriation of the Rohingya.

Guterres, who served as UN high commissioner for refugees for 10 years, said the UN refugee agency was consulted about the agreement but is not a party to the deal as is usually the case for such repatriation plans.

The deal applies to approximately 750,000 Rohingya who fled to Bangladesh following two army crackdowns in Myanmar's northern Rakhine state in October 2016 and August last year.

Guterres said it was essential that the returns be voluntary and that the Rohingya are allowed to return to their original homes -- not to camps.

"The worst would be to move these people from camps in Bangladesh to camps in Myanmar," said Guterres who spoke to journalists after presenting his priorities for 2018 to the General Assembly.

UN member-states in December adopted a resolution condemning the violence in Rakhine state and requesting that Guterres appoint a special envoy for Myanmar.

The UN chief said he expects to make that appointment soon.

More than 650,000 Muslim Rohingya have fled the mainly Buddhist country since the military operation was launched in Rakhine state in late August.
