NEW YORK, July 22 (Reuters) - The U.S. Public Company

Accounting Oversight Board said on Tuesday it had revoked the

license of a Hong Kong firm and barred its owner for violating

audit rules related to companies operating in China, including

Luckin Coffee Inc.

The PCAOB said in a statement it had sanctioned Centurion ZD

CPA & Co and its owner Chan Kam Fuk and hit them with a civil

penalty of $75,000 for violating the board's rules and standards

in connection with its audit work for three firms.

The auditor failed to properly assess risk and get sufficient

audit evidence from Luckin in a 2022 opinion of the firm's 2021

financial reporting, the PCAOB said. The Chinese coffee firm in

2020 had settled accounting fraud charges with the SEC. The firm

and Chan failed to use information about the fraud in the

subsequent year's audit, PCAOB said.

Centurion also violated PCAOB standards in connection with

the audit of a second Chinese company and with audit procedures

for some subsidiaries of a Malaysian firm, the PCAOB said.

Chan and Centurion did not admit or deny the findings. A

lawyer for both did not respond immediately to request for

comment.
