Min Aung Hlaing, the military leader, left Russia again without being invited by anyone. On the Russian side, it is reported that he came because of his personal issues. For more than a year after the coup, no country recognized him, so he only went to Russia. Russia does not treat him equally. Now he only meets with low-level Russian officials. A person like him will not be ashamed.
Min Aung Hlaing did not receive a letter to appoint him as ambassador, so the British ambassador was expelled by the military council. They have even downgraded their weapons in retaliation to countries like Brunei that do not recognize them. The military council is still closed off in international affairs, but domestically it still holds all power.
