There is a truce in the Chinese Civil War, and in the Korean War. There has never been a peace agreement in either wars. So technically, they are still at war, just not shooting at each other. That makes almost all the high end chips in the world produced in technical war zones.What 'war with China'? Taiwan is not at war.
By the way, it has never officially changed its name from Republic of China to Taiwan. It still has a dormant claim to the rest of China.
