Reuters reports that Trump administration officials have urged the president to delist Chinese companies that trade on U.S. exchanges and fail to meet U.S. auditing requirements by January 2022, Securities and Exchange Commission and Treasury officials said on Thursday.

The remarks came after President Donald Trump tasked a group of key advisers, including Treasury Secretary Steve Mnuchin and SEC Chairman Jay Clayton, with drafting a report with recommendations to protect U.S. investors from Chinese companies whose audit documents have long been kept from U.S. regulators.

It also comes amid growing pressure from Congress to crack down on Chinese companies that avail themselves of U.S. capital markets but do not comply with U.S. rules faced by American rivals.

“We are simply leveling the playing field, holding Chinese firms listed in the U.S. to the same standards as everyone else,” a Treasury official told reporters in a briefing call about the report.

The U.S. Senate unanimously passed legislation in May that could prevent some Chinese companies from listing their shares on U.S. exchanges unless they follow standards for U.S. audits and regulations.

Democratic Senator Chris Van Hollen, who sponsored the bill described the recommendations as “an important first step,” but said that “without the added teeth of our bill, this report alone does not implement the requirements necessary to protect everyday American investors.”

The administration’s recommendations, if implemented via an SEC rulemaking process, would give Chinese companies already listed in the United States until Jan. 1, 2022, to ensure the U.S. auditing watchdog, known as the PCAOB, has access to their audit documents.

They can also provide a “co-audit,” for example, performed by a U.S. parent company of the China-based affiliate tasked with auditing the Chinese firm. However, companies seeking to list in the United States for the first time will need to comply immediately, the officials said.
