Tourism in some Chinese inland cities is seeing a boost as more nonstop international routes to the cities have opened up.

Cities such as Xi'an, Chengdu and Wuhan have been added to some airlines' international route networks for their rich tourism resources.

On Sept 3, Qatar Airways, one of the main airlines in the Middle East, launched its Chengdu-Doha route, the third international route in Chengdu added this year.
