What are the visa requirements for China people to travel to Bhutan?

All foreigners going to Bhutan must obtain visas issued by Bhutan Immigration Bureau before boarding the plane. They are required to show a visa release letter issued by the Bhutan Immigration Bureau when they check in. At your entry point, you will be asked to show your visa certificate, and the visa will be printed on your passport. Please note that the initial recommendation letter issued by the Ministry of Foreign Affairs is invalid for travel. Any passenger without a valid visa will be rejected at the check-in counter, and Bhutan Airlines will not be liable for any claim. Visas are issued by your licensed Bhutan tour operator directly through the online system or through foreign travel agencies.
