Rising number of outbound visitors from the mainland will promote growth among members

China, the world's largest tourism market for both domestic and outbound travelers, will be responsible for more than 500 million out-bound visits in the coming years. That will help to fuel the economic development of G20 members.

As an example, Li Jinzao, director of the China National Tourism Administration, said in 2015 that in the next five years, more than 150 million Chinese tourists will visit countries along the route of the proposed Belt and Road Initiative, spending about $200 billion.
