By arrest you mean arrest for committing a crime? That would be different to sanctions. As government officials they would be protected by diplomatic immunity. Huawei's Meng was a private citizen. Once these officials step down then theoretically they could face prosecution however. But that depends on whether they have violated any US laws, usually on US soil (but there are exceptions to that), involving transaction with US currency going through a US financial institution.
There is a category called universal jurisdiction where regardless of the nationality of the accused, or the place where the crime took place, they can be prosecuted. But those were traditionally limited to piracy, because pirates often commit their acts on the high seas away from territorial waters. Now some are arguing this should be extended to war crimes like genocide, mass rape, brutalizing civilians, etc, although that has received pushback from other states.
