It seems China's outbound tourists far exceed those coming in, and this can be attributed to a few key reasons. Firstly, the rising middle class in China has increased disposable income, leading to more international travel. Secondly, China's rigorous visa policies can deter potential inbound tourists. Additionally, the pollution problem in major Chinese cities is often a significant turn-off for international tourists. Lastly, there's also the appeal of experiencing different cultures, which naturally encourages outbound travel.
