The People’s Republic of China is stepping up its economic war on us, adding additional weapons to its arsenal. Those weapons include

a blacklist for foreign firms it deems hostile, a law authorizing punishment of any company that helps enforce U.S. sanctions on Chinese targets, a rule ordering Chinese parties to ignore those sanctions outright, and expanded powers for its antitrust regulators to kill cross-border merger deals on national-security grounds.

Two responses come to mind. One is that Mark Zuckerberg, Meta’s boss and controlling shareholder, should simply ignore the PRC’s order to unwind its acquisition of Manus. Meta should, instead, proceed with what it has already collected via Manus. The unwinding is strictly a matter between Manus and its government masters. To the extent the PRC then takes economic or legal action against Meta, that should finally demonstrate even to Zuckerberg the lack of utility in doing any sort of business within the PRC.

The other response is that all the players should proceed as though the PRC’s threat to sue or its actual suing have no effect. Such suits, occurring as they will within PRC courts, can have no effect outside the PRC’s borders. In the event the PRC then acts against those intermediate businesses with operations inside the PRC, see above.
