China-based companies will have to disclose more about their structure and contacts with the Chinese government before listing in the US, the Securities and Exchange Commission said on Friday.

Gary Gensler, the chair of the US corporate and markets regulator, has asked staff to ensure greater transparency from Chinese companies following the controversy surrounding the public offering by the Chinese ride-hailing group Didi Chuxing.

“I have asked staff to seek certain disclosures from offshore issuers associated with China-based operating companies before their registration statements will be declared effective,” Gensler said in a statement.

He added: “I believe these changes will enhance the overall quality of disclosure in registration statements of offshore issuers that have affiliations with China-based operating companies.”

The SEC’s new rules were triggered by Beijing’s announcement earlier this month that it would tighten restrictions on overseas listings, including stricter rules on what happens to the data held by those companies.

The Chinese internet regulator specifically accused Didi, which had raised $4bn with a New York flotation just days earlier, of violating personal data laws, and ordered for its app to be removed from the Chinese app store.

Beijing’s crackdown spooked US investors, sending the company’s shares tumbling almost 50 per cent in recent weeks. They have rallied slightly in the past week, however, jumping 15 per cent in the past two days based on reports that the company is considering going private again just weeks after listing.

The controversy has prompted questions over whether Didi had told investors enough either about the regulatory risks it faced in China, and specifically about its frequent contacts with Chinese regulators in the run-up to the New York offering.

Several US law firms have now filed class action lawsuits against the company on behalf of shareholders, while two members of the Senate banking committee have called for the SEC to investigate the company.

The SEC has not said whether it is undertaking an investigation or intends to do so. However, its new rules unveiled on Friday would require companies to be clearer about the way in which their offerings are structured. Many China-based companies, including Didi, avoid Chinese restrictions on foreign listings by selling their shares via an offshore shell company.

Gensler said on Friday such companies should clearly distinguish what the shell company does from what the China-based operating company does, as well as the exact financial relationship between the two.

“I worry that average investors may not realise that they hold stock in a shell company rather than a China-based operating company,” he said.

He added that companies should say whether they had received or were denied permission from Chinese authorities to list in the US, including whether any initial approval had then be rescinded.

And they will also have to spell out that they could be delisted if they do not allow the US Public Companies Accounting Oversight Board to inspect their accountants three years after listing.
