I don't know of any. One can speculate that probably on the margins there are, but as with defence export controls, to violate national law is extremely dangerous in the margins of commercial space. Basically, for the major space companies at least, until you get more and bigger private players from other countries in this game, the costs of being caught and what will happen to you are much too high, including for Elon Musk, so I'm not greatly concerned about it.
