As far as I know, states have norms regulating similar relations, for example, when political parties in another country are financed by corporations from another country. In such cases, there are certain obligations that must be fulfilled by the financed political party, whose legal form is (legal entity under public law). There are similar procedures, for example, I will tell you about the fact of Georgia: if the annual income of any organization operating in Georgia exceeds 20%, in such a case, it is obliged to register as a "foreign influence agent". As for your question, it seems more rhetorical than practical.
