To be fair China can rapidly setup factories in many countries or just use them as re-sellers. Heck many of the "Made in India" goods are just re-branded stuff from China. This is why the tariffs encompass everything, even remote deserted islands. If you don't tariff everywhere you leave a loophole open for China to potentially exploit.
(Note I am not saying I 100% agree with the near-global tariffs, but I can see why they cover so many regions.)
