The US has imposed sanctions on a Myanmar top general and three senior government officials, accusing them of human rights violations against the Rohingya Muslims.
The generals and their families are banned from entering the US.
US Secretary of State Mike Pompeo said there was evidence that the generals were involved in the violent crackdown on the Rohingya minority in 2017, and that abuses were continuing.
Myanmar’s government and military have condemned the sanctions.
Mr Pompeo said the sanctions had been prompted in part by a recent decision to give early release to soldiers convicted of extra judicial killings at the village of Inn Din in 2017.
They spent less time behind bars than two Reuters journalists, Wa Lone and Kyaw Soe Oe, who had been investigating the massacre. The two reporters spent more than 16 months in prison on charges of obtaining state secrets before being released in an amnesty on 6 May.
Mr Pompeo said: “We remain concerned that the Burmese government has taken no actions to hold accountable those responsible for human rights violations and abuses, and there are continued reports of the Burmese military committing human rights violations.”
He said the US was “the first government to publicly take action with respect to the most senior leadership of the Burmese military”, and that there was “credible information of these commanders’ involvement in gross violations of human rights”.
