Is there a relationship between Hong Kong Volkswagen Finance and Volkswagen Bank?

It's okay.

Hong Kong Public Finance has nothing to do with Public Bank. Hong Kong Volkswagen Finance is a financial institution in Hong Kong and has nothing to do with Volkswagen Bank. Volkswagen Bank is a bank headquartered in Frankfurt, Germany, and its history can be traced back to 1870. Although both companies have the word "Volkswagen" in their names, they do not have any equity or business relationship.
