Cambodian Prime Minister Hun Sen has threatened to "shame" Australia and block the release of a joint statement at a regional summit in Sydney next month if he faces pressure over a political crackdown at home.
The strongman has been chastised by Western countries for taking a hammer to Cambodia's democracy in recent months by dissolving the main opposition party, shuttering independent news outlets and pursuing critics in the courts.
In a speech yesterday the notoriously brash leader said he would not tolerate any pressure on domestic politics when he attends a summit of the 10-member Association of Southeast Asian Nations (ASEAN) hosted by Australia in March.
"If you treat me inappropriately, I will hit back and leave shame on your face at the scene," Hun Sen added.
It would not be the first time Cambodia has used its intransigence to block or dilute an ASEAN statement.
In 2012 ASEAN foreign ministers failed to release a joint communique for the first time at the end of their annual gathering, with the Philippines blaming event host Cambodia for blocking criticism of Beijing's actions in the South China Sea.
Cambodia was also accused of forcing the group to water-down criticism of Beijing in a statement issued at the end of a 2016 meeting.
Cambodia's crackdown in recent months has pushed the country closer to China, which has lavished the country with cash, while rattling relations with the US and EU, who pulled support for July elections after the opposition was disbanded.
