Sanctions?

It depends on what the sanctions imply. For EU, there aren't even any sanctions against Huawei. There are some recommendations and national sanctions, but they are limited to telecommunications equipment.

On the other hand, for the Russian cases, the wording is very strong: "No funds or economic resources shall be made available, directly or indirectly, to or for the benefit of natural persons or natural or legal persons, entities or bodies associated with them listed in Annex I."

US wording is even stronger: "These prohibitions include the making of any contribution or provision of funds, goods, or services by, to, or for the benefit of any blocked person and the receipt of any contribution or provision of funds, goods, or services from any such person."

The Huawei sanctions are much more selective, as far as I know.
