SHANGHAI/BEIJING—A global stock rout earlier this week reminded investors about the power of the U.S. President’s Twitter account, but in China, where selling was heaviest, a ban on media coverage of his comments has raised questions about Beijing’s push to internationalize its capital markets.
President Donald Trump on May 5 tweeted that tariffs will increase on $200 billion of Chinese goods this week and target hundreds of billions more, reviving worries about continuing trade talks and knocking China’s stock benchmarks down over 5 percent.
