Art. 12. In cases where they deem it advisable in the interest of protected persons, particularly in cases of disagreement between the Parties to the conflict as to the application or interpretation of the provisions of the present Convention, the Protecting Powers shall lend their good offices with a view to settling the disagreement. For this purpose, each of the Protecting Powers may, either at the invitation of one Party or on its own initiative, propose to the Parties to the conflict a meeting of their representatives, and in particular of the authorities responsible for protected persons, possibly on neutral territory suitably chosen. The Parties to the conflict shall be bound to give effect to the proposals made to them for this purpose. The Protecting Powers may, if necessary, propose for approval by the Parties to the conflict a person belonging to a neutral Power, or delegated by the International Committee of the Red Cross, who shall be invited to take part in such a meeting.
