China's northwest regions are planning to invest more in air transportation in coming years, aiming to unlock the potential of Silk Road tourism through better connectivity.

Shaanxi province, whose capital, Xi'an, was the starting point of the ancient Silk Road, will increase flights with nations involved in China's Belt and Road Initiative.

The initiative refers to the Silk Road Economic Belt, which will link China with Europe, and the 21st Century Maritime Silk Road, a sea route stretching from southern China to Southeast Asia and Africa. The added Silk Road in the air is also expected to contribute to tourism development.
