HONG KONG — China on Wednesday moved to pump more cash into its financial system, suggesting that Beijing remained concerned about faltering growth despite signs that the world’s second-largest economy was stabilizing.

China’s central bank, the People’s Bank of China, announced that it would inject about $115 billion into the economy by freeing up banks to lend more money. The move comes after a similar action in September.

The change, announced on the New Year’s Day holiday, is likely to focus renewed attention on the health of the Chinese economy, a major driver of global growth. The move is relatively modest given the vast size of the Chinese economy, but the timing suggests that the country’s leaders are on high alert for new evidence of a slowdown. It follows a recent meeting of the country’s top economic planners and comes just weeks before Beijing releases closely watched estimates of year-end growth.

China’s leaders are contending with the country’s slowest pace of growth in nearly three decades.

The country’s slowdown has sent ripples through the global economy. Germany narrowly avoided a recession last fall, and its manufacturing sector has slumped in part because of reduced demand from China. Other European countries have also seen growth slow and their industrial sectors contract.
