Canada’s arrest of Huawei Chief Financial Officer Meng Wanzhou is a stinging rebuke of Xi Jinping’s Chinese government. It exposes China’s economic malfeasance and undercuts Xi’s global economic agenda.

While it’s not clear why Meng has been detained, we do know that it is on request of U.S. federal authorities in New York. Suspicion has therefore risen that Meng might be accused of circumventing U.S. sanctions on Iran or North Korea. We’ll get more information next week. Regardless, by challenging China’s version of Apple Inc. in such an overt manner, the U.S. government is sending a clear signal to Beijing that it will no longer tolerate China’s global economic misconduct.
