Which route is the fastest and cheapest from Yunnan to Bangkok, Thailand?

Do you want to drive? Then only Man Kun Highway is optional. There are freight companies in Kunming and Banna, which can go through customs clearance procedures.

If you fly, Xishuangbanna can take China Eastern Airlines to Bangkok or Chiang Mai, and if you fly from Kunming, you can take China Eastern Airlines \ Thai Airways, which takes about 2 hours to Bangkok. China Eastern Airlines is the cheapest, which is generally not in the tourist season. It costs about 2,000 RMB one way, which is relatively cheap and can take about 25 kilograms.

For railways, not yet.
