Practice Relating to Rule 53. Starvation as a Method of Warfare
Section C. Blockades and embargoes that cause starvation
Sweden’s IHL Manual (1991) states:
Certain states have maintained that the prohibition against starvation shall apply without exception which would also mean its application against blockade in naval warfare. Other states have claimed that this method of warfare is the province of the international law of naval warfare, which, according to Article 49:3, shall not be affected by the new rules of Additional Protocol I. There is thus no consensus that the prohibition of starvation shall be considered to include maritime blockade.
