An alliance of Myanmar ethnic armed groups have accused the junta of repeatedly violating a China-brokered cease-fire in the north of the country this month and causing civilian casualties.
Beijing brokered a truce between the junta and what is often referred to as the "Three Brotherhood Alliance" in January after months of fighting that displaced more than half a million people near China's southern border.
The cease-fire allowed the alliance — made up of the Ta'ang National Liberation Army (TNLA), the Myanmar National Democratic Alliance Army (MNDAA), and the Arakan Army (AA) to hold swathes of territory it had seized in northern Shan state.
