WASHINGTON—A senior U.S. official told the Commerce Department’s enforcement staff this week that China’s Huawei should still be treated as blacklisted, days after U.S. President Donald Trump vowed to ease a ban on sales to the firm.
Trump surprised markets on June 29 by promising Chinese leader Xi Jinping on the sidelines of the G-20 summit in Japan that he would allow U.S. companies to sell certain non-sensitive products to Huawei Technologies Co.
