Myanmar’s military rulers are again seeking to replace the country’s ambassador to the United Nations, who opposed their Feb. 1 ouster of the NLD and takeover of the government, AP reported.

Foreign Minister Wunna Maung Lwin says in a letter to U.N. Secretary-General Antonio Guterres that he has appointed Aung Thurein, who left the military this year after 26 years, as Myanmar’s U.N. ambassador. A copy of the letter was obtained Tuesday by The Associated Press.

Lwin said in an accompanying letter that Kyaw Moe Tun, Myanmar’s currently recognized U.N. ambassador, “has been terminated on Feb. 27, 2021, due to abuses of his assigned duty and mandate.”

The military’s previous attempt to oust Tun failed and there has been no reported action on the foreign minister’s letter, which is dated May 12.
