China, Russia and Mongolia have signed a string of cross-border tourism cooperation agreements as part of efforts to promote the construction of an economic corridor that spans the three countries.

The 10 cooperation projects, worth a combined 1.4 billion yuan ($220 million), were signed by government authorities and enterprises during the first China-Mongolia Expo, which opened Friday in Hohhot, capital of North China's Inner Mongolia Autonomous Region.

The projects include cross-border tourism route development and tourism personnel training in addition to hotel and resort zone construction. The trilateral cooperation relates specifically to a tourism route linking Hohhot, Ulaan Baatar, Ulan-Ude and Irkutsk.

"Cross-border tourism is an important part and platform of the China-Mongolia-Russia economic corridor," said Wei Guonan, head of the Inner Mongolia Tourism Administration.
