China's banking watchdog has ordered strict control of financial risks related to real estate as bank loans to the sector surged.

Regulations over property loans must be rigorously implemented, and financial business related to real estate agents and developers should be conducted in a prudent manner, according to a statement on the website of the China Banking Regulatory Commission (CBRC).

Irregular inflow of loans or wealth management funds into the property sector must be banned, said the statement.

By the end of September, financial institutions in China had lent 25.33 trillion yuan ($3.74 trillion) to the property sector, up 25.2 percent year on year, central bank data show.

While the property sector has been a significant growth driver for the Chinese economy so far, policymakers have tried to prevent an asset bubble following drastic price rises in some first- and second-tier cities.

As a result of government curb policies, including purchase limits and tightened mortgage restrictions, the month-on-month price index for new homes in 15 first- and second-tier cities retreated in the first half of October from September, according to the National Bureau of Statistics.

The CBRC also urged efforts to avert risks related to local government debts and industrial sectors with excessive capacity.
