BEIJING - China's central bank plans to issue 25 billion yuan (about US$3.69 billion) worth of bills in Hong Kong next Monday.

The move aims to enrich yuan-investment products with high credit ratings in Hong Kong and improve the yield curve of yuan in the region, the central bank said

The central bank bills will be issued in two batches. One batch is worth 10 billion yuan with a maturity of three months, or 91 days. The other batch is worth 15 billion yuan with a maturity of one year, the People's Bank of China said in a statement.
