Dim sum bond
From ACT Wiki
A bond denominated in Chinese renminbi, but issued and settled outside the People's Republic of China.
Developing from 2007 in Kong-Kong, initially the issuers were PRC and HK banks. As Chinese restrictions eased somewhat from 2010, Chinese non-financial companies (corporates), foreign banks, foreign corporates and eventually foreign regional governments and sovereigns made issues.
The offshore renminbi is known as CNH.
