China’s top Internet regulator publicly challenged the president of Qualcomm saying half the company’s revenue comes from China and that “we should make money together.” The comments Wednesday from Lu Wei, China’s minister of cyberspace affairs, come amid an investigation into the U.S. chipmaker by Chinese antimonopoly officials. Qualcomm has said it is cooperating. Mr. Lu was speaking during a session on the Internet at the World Economic Forum in the north-eastern Chinese city of Tianjin. Paul Jacobs, Qualcomm’s executive chairman, sat to his left. Mr. Jacobs declined to comment on a question from a Chinese reporter about the antimonopoly probe.
