Chinese banks must conduct due diligence on their businesses and report any potential risks to the China Banking Regulatory Commission (CBRC), the newspaper reported, citing CBRC chairman Liu Mingkang.

The regulator will pay keen attention to "shadow banking" businesses as well as off-balance-sheet banking activities involving deals with trust companies in a bid to prevent the type of excessive leveraging that brought down Lehman Brothers, the article cited Liu as saying.
