BEIJING, May 15 (Xinhua) -- China's central bank skipped open market operations Wednesday citing reasonably sufficient liquidity in the banking system.

Meanwhile, 10 billion yuan (1.46 billion U.S. dollars) reverse repos matured Wednesday.

A reverse repo is a process by which the central bank purchases securities from commercial banks through bidding, with an agreement to sell them back in the future.

China will keep its prudent monetary policy "neither too tight nor too loose" while maintaining market liquidity at a reasonably ample level in 2019, according to the annual Central Economic Work Conference held last year.
