In parts of Asia such as Singapore and Hong Kong, Christian names are not the same as given (first) names. For example, Mr. 李光耀 has the last name "Lee" and the given names "Kuan Yew", but his Christian name is "Harry". This doesn't necessary mean they are Christian though: in Singapore, virtually everybody has Western nickname used by army buddies, coworkers who speak a different language and so on. Jayanth becomes Jay, Meng Hong becomes Mike, and women in particular seem to have a predilection for adopting utterly improbable names that they find stylish (Xynthia, Konstanze, etc).
