Unless the treaty otherwise provides, or it is otherwise agreed, the withdrawal of an objection to a reservation becomes operative only when notice of it has been received by the State or international organization which formulated the reservation.
除条约另有规定或另有协议外，对保留提出之反对撤回，自提出保留之国家或国际组织收到撤回反对之通知时方始发生效力。
