As the world's biggest spenders, Chinese mainland tourists spent $261 billion in 2016, accounting for nearly 21 percent of the world's tourist consumption.

The report also said that Chinese mainland's outbound tourism has enjoyed double-digit growth for 12 consecutive years.

Countries, including the United States, Canada and Singapore, now issue 10-year visas to mainland tourists, helping China's tourism market.

In addition, China opened 260 international airlines from January to November last year, stimulating demand.

According to the report, Chinese mainland travelers made more than 120 million outbound trips in 2015, 313 percent more than 2005.

Figures released by the World Economic Forum in 2017 show that tourism last year stimulated the economy by generating over $7.6 trillion globally, supporting over 292 million jobs, or one in ten jobs worldwide.
