Reposting my comment in Myanmar here to answer. It isn’t on charm offensive. This situation is interesting because China is the one arming both sides of the conflict. China is the chief arms supplier to the military Junta whose weapons have been killing civilians. It is with Chinese blessing and Chinese weapons that guerilla group Brotherhood Alliance launched its 1027 operation last year that’s been highly successful against the Junta.

China has in the past gone alone (while rejecting participation of regional and other global powers) in brokering peace in Burma forcing both the Junta and the guerillas to sit down at meetings in southern China without participation of other regional countries. China has been the one meeting with Burma’s current and former dictators in past two months, including Wang’s visit to Myanmar 2 days ago.

In an about-face, China is now seeking greater regional cooperation in Burma’s internal affairs. It may well be that the situation is spinning out of control for China, and Chinese are worried their strategic interests are now poised to crumble in Myanmar.
