The move effectively rolled over 383 billion yuan worth of medium-term facility loans that were maturing on the same day and added even more cash.
The interest rate for the one-year MLF was 3.30 percent, the People's Bank of China (PBOC) said, the same as in the previous such operation.
The PBOC also injected a net 30 billion yuan into money markets on Thursday through seven-day reverse bond repurchase agreements. The bank left the interest rate on the seven-day tenor unchanged at 2.55%.
