US regulators have selected e-commerce majors Alibaba Group Holding Ltd and JD.com Inc among other US-listed Chinese companies for audit inspection starting next month, people with knowledge of the matter have told Reuters.

The selection follows a landmark audit deal between Beijing and Washington on Friday that allows US regulators to vet accounting firms on the mainland and in Hong Kong, potentially ending a long-running dispute that threatened to boot more than 200 Chinese companies from US stock exchanges.

The tech duo along with Yum China Holdings Inc - owner of KFC, Taco Bell and Pizza Hut restaurants in China - have been notified that they are among the first batch of Chinese companies whose audits will be inspected in Hong Kong by US audit watchdog, the Public Company Accounting Oversight Board (PCAOB), the sources said, declining to be identified due to confidentiality constraints.

The respective accounting firms of Alibaba, JD.com and Yum China - PwC, Deloitte and KPMG - have also been notified of the inspection, they added.

Alibaba, JD.com, Yum China, KPMG and the China Securities Regulatory Commission did not respond to requests for comment.

Spokespeople for PwC and Deloitte said it was company policy not to comment on client matters.

A PCAOB spokesperson on Tuesday said the board did not comment on inspections. The watchdog could not be reached for comment outside of US business hours on Wednesday.

Alibaba's US-listed stock closed down nearly 3 percent on Tuesday after the Reuters' report, having been up about 1 percent in pre-market trade.

US regulators have for more than a decade demanded access to audit papers of US-listed Chinese companies, but Chinese authorities have been reluctant to let US regulators inspect accounting firms in China, citing national security concerns.

Alibaba, which went public in New York in 2014 in what was at the time the largest listing in history, is the most valuable Chinese firm listed in the United States with a market value of US$248 billion as of Tuesday.

The PCAOB on Friday said it had notified the selected companies, without naming them, and that it expects its officials to land in Hong Kong, where the inspections will take place, by mid-September.

The regulator, which oversees audits of US-listed companies, said it selects companies based on risk factors, such as size and sector, and that no companies could expect special treatment. (Reuters)
