No GPP member state may supply or transfer weapons, military equipment, or security-relevant technologies to a state that is classified as an aggressor state or is conducting a war of aggression in violation of international law.The transit of such goods through the territory of a GPP state – by land, water, or air – is likewise prohibited if they benefit an aggressor state.
Permissible, however, is the support of non-aggressive states engaged in legitimate self-defense (cf. Art. 13a para. 2b).Such deliveries may only be made via secure GPP member states or third countries, and under no circumstances through the territory of an aggressor.
