Political fealty is one of the major takeaways for China. Xi is not stupid, but he has made a system that is effectively blind due to his setup as Emperor.
TWN is not slow on the uptake. They would do well to add MANPADS by the gross distributed within the whole area of the country, along with ATWs.
Long term I can see a future for TWN, PRC is heading over a cliff and will have real issues within its own kingdom, from food insecurity, property bubble collapse, the whole house of cards deal, demographics, a decline in globalization that appears to be well underway from the last few years of logistical failures. TWN is smart enough and driven to maintain a defense that can outlast Xii's hold on power.
Ukraine is a learning opportunity all round, assuming that it is survived.
Hopefully a cautionary tale as well, militarily, economically and geo-politically. Can’t imagine Xi wanting China to be marginalized the way Russia has become.
