Today, I was chatting with friends in SG about this topic. What’s being pursued isn’t just investment income, but all income. China has a global taxation system. For Chinese tax residents, those who meet the criteria of having a 'domicile' in China or staying in the country for a cumulative 183 days in a year are, in principle, subject to global income taxation. This includes not just investment income but also salaries and wages. That said, if you’ve already become a tax resident in another country (not necessarily through immigration or permanent residency), that country generally won’t share its tax resident information with other countries during the period you’re a tax resident there. Taxation focuses on the place of tax residency, not your passport or nationality. Tax residency is the main factor influencing tax data exchange—at least for now.
