I don’t think FTA or pork bans has anything to do with it.
Countries all over the world trades with Taiwan, regardless of FTA, tariffs, or whatever. Taiwan is a major player in the electronics, solar cell, textile, machine tool, and many more markets, and countries aren’t letting FTA or lack thereof stopping them from trading with Taiwan.
A lot of how Taiwan is treated is not official, basically “gentleman’s agreement”. They can’t officially recognize Taiwan as a country, have formal diplomatic ties, formal trade relations, etc. but it’s telling that Taiwan is a major EU trading partner. They may not give Taiwan formal recognition in anything (and a lot of them don’t mean much quite frankly but are purely symbolic), but they treat Taiwan as a country. Every country except PRC accepts Taiwanese passport, stamps visas on them, and Taiwan has visa free entry to over 140 countries. China doesn’t say a thing unless it’s “formal” which doesn’t mean much anyways.
Taiwan wage is low because Taiwanese bosses are greedy and has a mentality that employees are not valued but just hired hand to do slave work. The government is trying but they aren’t trying to be heavy handed. The low wage most likely kept rental prices low, vastly lower than what their purchase price would suggest (landlords won’t raise residential rent because they’d lose tenants, and empty houses break down very quickly). It also kept inflation low. In America inflation is much more out of control and any rise in wage is quickly multiplied in cost increase of EVERYthing else, from rent to consumer prices! I mean stuff like education and healthcare, pretty much 1000% inflation increase.
Taiwan does not have much of a beef industry to speak of, everything is either American or Australian. The only cows you will ever see is the one you see on Yangming Shan and the few dairy cows they keep around. Taiwan lacks the land for grazing to make raising cattle sustainable.
Again, wages has nothing to do with trade, and eliminating a little bit of tariff isn’t going to magically increase the worker’s wage (and if the wage does increase, rent will also increase tenfold). Taiwan trades with so many countries you’d wonder how a country this size can manage to do it.
