That's not quite the same because we recognise the copyright in domestic law. American copyright laws aren't being directly applied in other countries - different countries can have different laws on dealing with copyrighted material.

Sure, but if you violate those laws and then travel to that country they're completely allowed to persecute you. That's what happened to the Huawei exec (or to be more specific, she traveled to a country with extradition treaties with the US).

Nope, you cant. This is like saying if I smoke weed in a country where it is legal and then go to a country B where it is illegal. Country B can arrest me because I broke their law.

Copyright law is a domestic law. You cannot be prosecuted for break US copyright law if you broke the law in an unrelated country B and you are not US citizen. Also B doesn't recognize US's jurisdiction to enforce copyright law in that country.

This is the case for several countries, such as South Korea: https://www.theguardian.com/world/2018/oct/23/bong-arm-of-th...

In Huawei's case even domestic law doesn't apply to them. Its like a canadian citizen being arrested in South Korea for smoking weed in Canada

Huawei broke international treaties. My understanding is that violation of such treaties is enforceable by any signatory. It's more like someone laundering money in one country and getting arrested in another country that is a signatory of an international anti-laundering law.

If this weren't the case, then international treaties would be pointless. Countries just wouldn't bother enforcing them against their own citizens.
