The Senate overwhelmingly approved legislation on May 20 that could lead to Chinese companies such as Alibaba Group Holding Ltd. and Baidu Inc. being barred from listing on U.S. stock exchanges amid increasingly tense relations between the US and China. The bill, introduced by Senators John Kennedy, a Republican from Louisiana, and Chris Van Hollen, a Democrat from Maryland, was approved by unanimous consent and would require companies to certify that they are not under the control of a foreign government. If a company can’t show that it is not under such control or the Public Company Accounting Oversight Board isn’t able to audit the company for three consecutive years to determine that it is not under the control of a foreign government, the company’s securities would be banned from the exchanges. The Bill now requires to be passed by the House and then signed by the US President. It could potentially lead to the delisting of 800 companies owned by the Chinese  government and its entities.
