In addition to opposition from the people, Taiwan literally can't buy Sinovac, the law simply does not allow importing vaccines that are made in China. Meanwhile, that negotiation between biontech and Taiwanese government happened. Biontech wanted a minimum ordering quantity of 30M jabs, but the Taiwanese government is only willing to purchase 2M jabs because they've bought 5M jabs from Moderna and wants to rely on locally produced vaccines (Medigen). Also, at that time, Taiwan pretty much have 0 domestic cases and it's life as usual, and demand for vaccine is pretty weak.

> Taiwan asserts ownership over all of mainland China (actually this view varies depending on which political party gets elected)

That's 30 years outdated. There's two major political party in Taiwan, out of the two, DPP supports the independence of Taiwan ( but doesn't claim the ownership of mainland China ).

Some politicians wanted Taiwan to be in UN, but almost everyone knows that it's impossible.

> Taiwan with its democracy is more corrupt than the CCP, just look at Chen Shui-bian.
In 2004, the day before the presidential election, Chen Shui-bian got shoot (it hit his ankle). Rumors says that it's his own arrangement to shoot himself, in order to win the election, and he did.

Many in Taiwan agrees that he's corrupting the government, as the economy isn't going well since the year (2000) he's elected.

> look at how Taiwans native tribes were treated by the Taiwanese Hans who took over.
In national wide university admission examination ( something like SAT/ACT ), they get 30% extra bonus. Therefore, that's say that I need 450 points out of 500 in order to get into the best university in Taiwan ( National Taiwan University ), they only need 350 points out of 500 points. I would say they are quite well-treated nowadays.
