BEIJING, Aug. 6 (Xinhua) -- The People's Bank of China (PBOC) said Tuesday that it will issue 30 billion yuan (about 4.3 billion U.S. dollars) of central bank bills in Hong Kong on Aug. 14.

Among the total, 20 billion yuan will mature in three months and 10 billion yuan will mature in a year, the PBOC said on its website.

To help expand the range of yuan-denominated financial products with high credit ratings in Hong Kong, the PBOC first issued such bills there in November 2018, raising 20 billion yuan.

It issued the same amount of bills in February, May and June this year.
