The CONTRACTING PARTIES may consult with contracting oarties, with the Economic and Social Council of the United Nations and with any appropriate inter-governmental organi- zation in cases where they consider such consultation necessary. If the CONTRACTING PARTIES consider that the circumstances are serious enough to Justify such action, they may authorize a contracting party or parties to suspend the application to any other contracting party or parties of such obligations or concessions under this Agree- ment as they determine to be appropriate in the circumstances. If the application to any contracting party of any obligation or concession is in fact suspended, that contracting party shall then be free, not later than sixty days after such action is taken, to advise the Secretary-General of the United Nations in writing of its intention to withdraw from this Agreement and such with- drawal shall take effect upon the expiration of sixty days from the day on which written notice of such withdrawal is received by him.
