Burma's military frequently clashes with several groups who say they are fighting for greater autonomy for ethnic minorities in the area, through which much of Burma's foreign trade flows.
The fighting erupted at Muse town yesterday in which nineteen people have been killed so far.
According to a report from GGRAsia citing an earlier story from the Reuters news service, the assault by about 100 members of the Ta'ang National Liberation Army took place on Saturday morning in the Shan state border community of Muse and also involved attacks on local security checkpoints.
Pointing out that at present, relevant parties in Myanmar are actively preparing for the third meeting of the 21st Century Panglong Peace Conference and China has been providing required assistance in this regard, the statement voiced firm opposition to any attempt to undermine peace and stability along the China-Myanmar border and any act deliberately obstructing the Myanmar peace process. "Owing to the Tatmadaw's massive reinforcements in Ta'an State and fierce battles with (Kachin Independence Army) KIA in Kachin State, this small campaign was organised", the TNLA said.
Condemning the violent incident and saddened by the injuries and death of the innocent people, China has urged the parties concerned to ensure life and property safety of the two countries' inhabitants in the border area.
China called for all parties to "exercise restraint", implement a ceasefire, and prevent the situation from escalating, so as to restore peace to the China-Myanmar border region.
Violence on the Myanmar side of the border has in recent years sent thousands fleeing through the rugged mountain terrain into China, where the Chinese government at times has set up relief camps.
Such conflict has frayed ties between China and Myanmar, which Beijing has hoped could be a key gateway in its multi-pronged "One Belt One Road" strategy to promote regional economic links.
