The U.N. Security Council is considering action to push Myanmar to work with the United Nations to address the Rohingya refugee crisis, although China and Russia have so far boycotted talks on a British-drafted resolution, diplomats said Monday.

The draft resolution aims to put a timeline on Myanmar allowing the return of more than 700,000 Rohingya Muslim refugees from neighboring Bangladesh and addressing accountability, diplomats said, speaking on the condition of anonymity.

The Rohingya have fled Myanmar's Rakhine state since August last year, when attacks on security posts by Rohingya insurgents triggered a military crackdown that the United Nations, the United States, Britain and others described as ethnic cleansing.
