EU and US have "well-established principles of international law, such as respect for the sovereignty and territorial integrity of other states" to identify, seize, and "freeze" real property and financial assets held by persons who violate national security laws."

China enforces its national security laws and constantly avers state obligations to "international laws" and UN Conventions. Until further notice, I presume China will apply those "well-established principles" and procedures (as precisely explained by US Treasury Sec Yellen, for example, and EC President vdL) to arrest proceeds from beneficial ownership entitled to persons who violate its own national security laws.

Yes, I'm not going to search for either an official statement published by the Chinese MoF or applicable provisions of Chinese civil code. I've wasted enough energy on revealing EUR LEX and USC. You try it!
