Communication Flows in International Economic Law
The right to admission of foreign investment is universally considered under general international law as being an absolute right of the State. Thus, it has been stated:
From the perspective of general international law, states are in no way compelled to admit foreign investment.
The right of a state to control the entry of foreign investment is unlimited, as it is a right that flows from sovereignty.
The right is absolute and can only be restricted by international agreement.
