1. After the expiry of five years from the entry into force of this Convention, a State Party may propose an amendment and transmit it to the Secretary-General of the United Nations, who shall thereupon communicate the proposed amendment to the States Parties and to the Conference of the States Parties to the Convention for the purpose of considering and deciding on the proposal. The Conference of the States Parties shall make every effort to achieve consensus on each amendment. If all efforts at consensus have been exhausted and no agreement has been reached, the amendment shall, as a last resort, require for its adoption a two-thirds majority vote of the States Parties present and voting at the meeting of the Conference of the States Parties.
一、缔约国可以在本公约生效已经满五年后提出修正案并将其送交联合国秘书长。秘书长应当立即将所提修正案转发缔约国和缔约国会议，以进行审议并作出决定。缔约国会议应当尽力就每项修正案达成协商一致。如果已经为达成协商一致作出一切努力而仍未达成一致意见，作为最后手段，该修正案须有出席缔约国会议并参加表决的缔约国的三分之二多数票方可通过。
