Realistically lots of multi-national companies have an EU presence, so concerns about “violating sovereignty” are sorta moot. Huawei probably wants to do business in the EU which requires following EU law. As an aside: in general a sovereign country can do whatever they want in their own territory, this includes the right of the country to bind itself to treaties. So in your hypothetical, > Does your home country observe the EU’s violation of its sovereignty and throw you in a home country jail? This doesn’t look like a violation of sovereignty to me; the non-EU has decided to enforce an EU law. Why? I don’t know, maybe it makes business easier for the multinational companies of the non-EU country. Countries can also do things like apply secondary sanctions to an entity. So, again hypothetically, the EU doesn’t need to be able to enforce a ruling against you. They can make you toxic to anyone who wants to do business in the EU.
