The People's Bank of China injected 60 billion yuan (about 8.49 billion U.S. dollars) into the market through seven-day reverse repos at an interest rate of 2.2 percent, according to a statement on its website.
The move aims to keep liquidity in the banking system at a reasonably sufficient level, the statement said.
As no reverse repos matured Tuesday, this led to a net injection of 60 billion yuan into the market.
A reverse repo is a process in which the central bank purchases securities from commercial banks through bidding, with an agreement to sell them back in the future.
China will pursue a prudent monetary policy in a more flexible and appropriate way, according to this year's government work report.
The country will use a variety of tools including reserve requirement ratio cuts, interest rate reductions and re-lending to enable M2 money supply and aggregate financing to grow at notably higher rates than last year, said the report.
