China outbound tourism has increased by 1,380% since 2000, and is poised to account for 25% of global tourism by 2030. In 2016, Chinese tourists spent $261.5 billion, double the amount spent by US tourists ($123.6 billion).
Only seven percent of Chinese hold passports, while 40 percent of Americans have passports. This means that although Chinese tourism rates have only just begun, there is more room for growth.
The figures clearly show why countries like Britain are doing their best to woo Chinese tourists with naming campaigns, and other activities, to attract Chinese tourists and their yuan.
