Canadian authorities said they nabbed top executive Meng Wanzhou, the daughter of Huawei’s founder, in Vancouver Saturday at the request of U.S. law enforcement. Although her charge is not known, Nebraska Sen. Ben Sasse connected Meng’s arrest with alleged circumvention of economic sanctions against Iran. Shenzhen-based Huawei recently surpassed Apple as the world’s second-biggest smartphone maker. The arrest is sure to complicate delicate U.S.-Chinese tariff negotiations started at last weekend’s G-20 Summit. China has demanded Meng’s release, saying she had not violated any American or Canadian laws.
