Shang said the commission will take various measures to manage the risks of lending to local government funding vehicles, including controlling the total loan amount, increasing asset-backed financing and establishing a long-term mechanism to push forward the optimization of the credit structure of local governments.

The precise amount of regional and local government-related debt outstanding is unknown. In June, the National Audit Office published a more limited survey of 15 provinces, three municipalities, 15 provincial capital cities and three districts. It showed their debt had continued to rise but at a relatively modest level of 13 percent over the two years up to 2012, the note said.

"China's audit of local government debt will improve transparency," said Katie Chen, an analyst with the sub-sovereign group at Moody's Investors Service Beijing Ltd.

In response to mounting concerns over trusts and wealth management products - which are considered to be "shadow banking" by many people - Shang said the risk element in these products is controllable.

"Growth rates of such products are not significant. The balances of these products are basically the same as that of last year," said Shang.

The balance of wealth management products was 9.08 trillion yuan by the end of June, with non-standard credit assets totaling 2.78 billion yuan, 7 percent short of the level recorded in late March, when the commission released a notice on regulating the wealth management product business of the country's commercial banks.

Shang said risk pressures increased in the first half of 2013 when there was a slightly higher non-performing loan rate at 0.96 percent because of the short-term volatility of the money market.

Lenders need to keep a close eye on their liquidity management, said Shang.

"The liquidity crunch in June was a lesson to lenders that at all times the management of lenders must follow the principle of prudence. Safety and liquidity are always vital in the banking sector and financial system," said a CBRC note on Friday.
