I did know that achieving Chinese citizenship meant giving up his Canadian citizenship. For ease of world travel alone, the Canadian passport is a great lifeline. Giving it up is a bold move.
Let me put it this way. From all Mr. Zeman continues to achieve both professionally and in the service of HKSAR and other organizations, if officials of HKSAR didn't look to see what more he can contribute to HKSAR and China, they'd be rather foolish it seems. His qualifications and experience here speak for themselves.
I have not met this man but he strikes me as a good public citizen as much as he is a successful businessman. Most countries can use more like that and if Mr. Zeman turns up in higher office sometime, that seems to be a good thing.
I know how much my province (BC) and specifically my university benefited from two descendants of Jewish immigrant families - Jack Diamond (a good friend now deceased) and Joe Segal (another good friend)- both former Chancellors at Simon Fraser University and great citizens of our province and city.
