The strategic tourism promotion agreement has been signed between the five provinces in northwest China -- Shaanxi, Gansu, Ningxia, Qinghai and Xinjiang.

They are planning to promote five distinctive tourism brands: the Silk Road, Yellow River Culture, the Great Wall, the Long March, and the Qinghai-Tibet railway.

A unified logo and billboard style will be adopted to promote the five brands and the provinces will work together on the design of the promotion materials. Besides mutual promotion between these provinces, they will also exchange links on their tourism web portals.

Also, there is a tourism trade fair which will be held in one of the five provinces each year from 2010 in order to build a tourism platform in northwest China.
