This work will show that all isolated proposals for the solution of the extraterritoriality problem are fundamentally insufficient. Only a combination of negotiation, agreements and arbitration comes near to a solution of the problem. Taking the example of antitrust and export control laws the author will describe and analyze the different approaches currently discussed to cope with the fact that one sovereign state tries to extend its jurisdiction into the field of another sovereign state. It is to be shown that no approach can succeed as long as the substantive laws in the antitrust and export control field are different.
