WASHINGTON (Reuters) - President Donald Trump did not know about a U.S. request for the extradition of Huawei’s chief financial officer from Canada before he met with Chinese President Xi Jinping over dinner last weekend, a White House official said on Thursday.

Huawei Technologies Ltd’s CFO Meng Wanzhou, the daughter of the company’s founder, was arrested in Canada on Dec. 1 and faces extradition to the United States. The United States has been looking since at least 2016 into whether Huawei violated U.S. sanctions against Iran.
