An article from Reuters says;

People’s Bank of China (PBOC) is “set to inject about 200 billion yuan ($32.66 billion) worth of three-month loans into five or six listed banks to keep liquidity ample and support the slowing Chinese economy, four sources with knowledge of the matter said on Friday”…

“Banks got the notice this afternoon but perhaps will only receive the funds next week. This injection focuses on listed joint-stock banks,” one source said.
