Beijing is preparing to make a concession on the disclosure of Chinese audit information in an effort to resolve an impasse threatening more than $2tn of shares in US-listed Chinese companies.

The plans could result in some Chinese companies that are listed in the US being able to provide some audit information to US accounting regulators, according to three people familiar with the matter. They would also clarify what information can and cannot be disclosed abroad, the people said.

The move towards a resolution of the long-simmering tension over foreign access to Chinese company audit papers comes a week after the Securities and Exchange Commission threatened to delist some Chinese companies from US exchanges. The threat prompted a sharp fall in Chinese tech stocks.
