A U.S. Treasury official said Saturday there are no current plans to stop Chinese companies from listing on U.S. exchanges, a day after a report that the Trump administration is discussing ways to limit U.S. investors’ portfolio flows into China.

“The administration is not contemplating blocking Chinese companies from listing shares on U.S. stock exchanges at this time,” Treasury spokeswoman Monica Crowley said in an emailed statement.

Crowley was responding to Friday’s Bloomberg News report on various measures under consideration by the United States, including delisting Chinese firms from U.S. exchanges. The report unnerved markets, with the S&P 500 Index closing about 0.5 percent lower. U.S.-listed shares of China-based companies, such as Alibaba Group Holding and Baidu Inc., tumbled.

Other potential measures include limiting Americans’ exposure to the Chinese market through government pension funds, and ways to put caps on the Chinese companies included in stock indexes managed by U.S. firms, according to people familiar with and involved in the discussions. Crowley’s statement didn’t address or rule out any of those possibilities.

Trump administration officials for weeks have been examining their options, and Treasury has been participating in inter-agency meetings chaired by Larry Kudlow, the National Economic Council (NEC) director, the people said.

Still, the push largely comes from Trump’s more hawkish aides, like White House trade adviser Peter Navarro, and outside advisers like Steve Bannon. The NEC and Treasury are wary of the market reaction and are working to ensure that any plan would be executed in a way that doesn’t spook investors, the people added.

People close to the administration Friday expressed annoyance at the discussions being publicized, saying that the White House hasn’t decided on a course of action. They said the discussions were examining a wide range of options and were therefore not yet ready for public consumption.

Some advocates of a crackdown on financial flows within the administration said they saw the fact the discussions were being leaked as an effort by doves inside the White House to kill the effort by stirring up opposition.

U.S. President Donald Trump has given the green light for the review, a person familiar with the deliberations said, but exact mechanisms or a timeline had not been worked out. (SD-Agencies)
