I can think of the German Cococola as one precident even if it is more local. Embargoes forced the German branch to split and develop their own independent supply chains. They remerged when possible. Effectively the solution has been an effective hard split into two companies one for each set of laws. They certainly have to sever monetary and organizational ties to not locally be engaged in conspiracy. Without coordination or assistance they have no responsibility to tbeir illegal twin abroad. They do what they can get away with locally and relying upon their counterpart's enforcement failures abroad. It may be illegal but if they are in another superpower's territory entirely they are protected. Being fully lawful to both at once was precluded so they effectively become mirror universe versions of themselves lawful in one and scofflaw in the other. Other less shady alternative approaches include withdrawing from one superpower and shifting their business entirely or simply deciding to dissolve themselves entirely and distribute their assets to the shareholders.
