According to PANews and the Financial Times, Chinese tax authorities have mandated a 20% tax on overseas stock profits with rigorous reporting and penalties for noncompliance.
Chinese tax authorities now require taxpayers to report and pay a 20% tax on overseas income from foreign stock transactions.

Oversight is strengthened through measures such as the Common Reporting Standard.
