WASHINGTON, March 11 (Reuters) - The International Monetary Fund said on Thursday it is “very concerned” about escalating tensions in Myanmar, but is refraining from most engagement with the country’s military rulers until the views of its members on the country’s political situation are clarified. “We are very concerned about the escalating tensions and their impact on the people of the country,” Rice told a regular news briefing. “A key immediate concern is ensuring that efforts continue to combat the COVID crisis and support the most vulnerable.” Rice said IMF staff are having only “low-level engagements such as fact finding” in Myanmar at the moment.
