China reviews audit firms

NEW YORK / SINGAPORE - China's financial regulators have asked the world's biggest audit companies to conduct an urgent review of their work on US-listed Chinese companies and provide them with details on information they may have provided to overseas regulators, two sources told Reuters.

The move is set to ratchet up tensions between US and Chinese financial regulators following a string of accounting scandals at US-listed Chinese companies.

Last month, the US Securities and Exchange Commission (SEC) asked a US court to enforce a subpoena it sent to Deloitte Touche Tohmatsu Ltd's China practice for work papers from its audit of scandal-hit Longtop Financial Technologies Ltd.
