The bank lowered medium-term lending rate by 10 basis points to 2.75% from 2.85%, according to a statement from the PBOC.
It also reduced the seven-day reverse repo rate to 2% from 2.1%, injecting 2 billion yuan (some $300 million) into the banking system.

Meanwhile, the world's second-largest economy saw slower-than-expected industrial production and retail sales growth, suggesting the zero-COVID policy continues to weaken consumer demand.
