A total of 500 billion yuan (about 74.21 billion U.S. dollars) was injected into the market via medium-term lending facility (MLF), according to the People's Bank of China.
The funds will mature in one year at an interest rate of 2.95 percent.
The MLF tool was introduced in 2014 to help commercial and policy banks maintain liquidity by allowing them to borrow from the central bank using securities as collateral.
Meanwhile, the central bank injected 50 billion yuan into the market through seven-day reverse repos at an interest rate of 2.2 percent.
China pursues a prudent monetary policy in a more flexible and appropriate way, according to this year's government work report.
