You're right, Icon. Plus, the guy is a greenie working under the Ma administration, so the last thing he wants is to come across as a sinophobe if he wants to keep his job. Hence the usage of "foreigners" as a catchall that included the "foreign" Chinese. But now that he's dragged down all foreigners, I'm pretty offended by his original facebook post:
“If foreigners choose to join Taiwan’s national health insurance system, that’s fine, but the premium should not be what it is now. Foreigners in the past have not made any contributions and not paid a penny in taxes, which is a very big difference from Taiwan’s citizens.”
Sinophobia or xenophobia, neither evil is less than the other.
