BEIJING, June 11 (Xinhua) -- The People's Bank of China (PBOC) plans to issue central bank bills in Hong Kong in late June, following three rounds of such issuance since November last year.

The move is aimed at improving the yuan yield curve in Hong Kong, the PBOC said in a brief statement on its website, without giving further details.

To help expand the range of yuan-denominated financial products of high credit rating in the region, the PBOC first issued bills in Hong Kong in November 2018 when 20 billion yuan (about 2.9 billion U.S. dollars) was raised.

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