Westerners working in China are officially on notice. You could be arrested on trumped up charges at any time and used as hostages to promote Community Party interests. That’s the message from the humiliating U.S. surrender to China’s hostage diplomacy in the case of Huawei chief financial officer Meng Wanzhou. Canadian authorities arrested Ms. Meng in 2018 at the request of the U.S., which charged her with bank and wire fraud. Under a deferred prosecution agreement (DPA) reached Friday, Ms. Meng was allowed to return to China without going to trial. She merely admitted to facts she had previously denied. Shortly thereafter, and right on cue, China released two Canadians it had arrested on phony charges not long after Ms. Meng’s arrest.
