There's no China-Thailand border, so you gotta go via Laos. [there is/was a Jinghong-Chiang Saen boat; even if it's running (not certain, as the Mekong is low at this time of year), it's something like 800 kuai a head.]
Cheapest would be bus to Mengla 勐腊, cross into Laos in Mohan 磨憨 www.gokunming.com/[...] then head via Luang Namtha to the Chiang Khong/Huay Xai/清孔 border crossing into Thailand.
Remember the formalities for the Laos visa (US$40 or so, photo, depends on your nationality) and remember that land-border entry to Thailand (as opposed to airport) only gives you 15 days rather than the usual 30.

Kunming stunned by cafe bombing
Posted by@tanfei: The 14:47 report is what we used to write the update. However, the content of that page has been added to since then, adding the eyewitness reports etc.
I should add that Salvador's is not owned (or co-owned) by Italians, as that story reports.
