360. Aid and assistance in the breach by a state or international organisation of its international obligations.

A state which aids or assists another state in the breach of an international obligation may thereby incur its own responsibility1. A state which provides aid or assistance is responsible for its own internationally wrongful act, consisting in the provision of the aid and assistance which assists the other state to breach its international obligation; it is not responsible, as such, for the act of the assisted state2.

It is necessary that the state providing the aid or assistance should have knowledge of the circumstances giving rise to the breach of its international obligations by the aided or assisted state3.
