China's central bank on Saturday published draft rules clarifying standard credit assets in a bid to better regulate the market and protect the interests of investors.

Standard credit assets refer to fixed-income securities, including treasury bonds, central bank bills, local government bonds, financial bonds and corporate bonds, the People's Bank of China said in a statement on its website.

Non-standard credit assets need to meet a number of requirements to be approved as standard credit assets, such as sufficient information disclosure, a sound liquidity mechanism and registration in qualified agencies, the statement said.

Public opinion will be solicited until Nov. 10.

Analysts said the draft rules were in line with previously released asset management regulations and made clarifications on financial products of market concern after adequate communication with market agencies, which are expected to have limited impact on the financial market.
