US Trade Representative Robert Lighthizer said on Sunday that US-China negotiations should not be impacted by the controversial arrest of a top executive from Chinese telecom giant Huawei. “This is a criminal justice matter. It is totally separate from anything I work on or anything that trade policy people in the administration work on,” Lighthizer said on CBS’ Face the Nation. Lighthizer’s comments come as China’s Vice Foreign Minister Le Yucheng summoned US Ambassador to China Terry Branstad on Sunday in protest over the arrest of Sabrina Meng Wanzhou, the chief financial officer of Huawei. Le urged the United States to drop the arrest warrant and cautioned that China “will respond further” depending on the US response.

Lighthizer, Trump’s top trade negotiator, outlined that the Trump administration expects China to agree to structural changes that will protect US technology and get additional market access for American businesses. “If that can be done, the president wants us to do it. If not, we’ll have tariffs,” he said.
