The Financial Post reports in its Thursday edition that executives from many of the biggest American companies, including Elon Musk's Tesla, and are converging on San Francisco this week for an audience with Chinese President Xi Jinping and other Asian leaders as long-frosty U.S.-China relations show tentative signs of warming. A Bloomberg dispatch to the Post says the for many corporations, the agenda is simple: They are ready to get back to business. A chief executive officer jamboree on the sidelines of the Asia-pacific Economic Cooperation meeting will coincide with the most challenging trade climate in a generation. Washington is trying to prevent China from acquiring high-end computer chips and has imposed curbs on U.S. investment there. Beijing has responded by jump-starting its own chip efforts and exhorting citizens to buy locally made phones and other products. In one sign of a potential thaw, the Chinese government is considering unveiling a purchase agreement for Boeing's 737 Max jetliner during APEC. Mr. Xi is not expected to announce a formal order for the plane, but a deal would be a significant breakthrough for Boeing, which has been largely frozen out of the Chinese market in recent years.
