The United States expressed deep regret following the failure of the Nuclear Non-Proliferation Treaty (NPT) Review Conference to reach a consensus on a final document, primarily due to concerns over Iran's nuclear activities. The conference, held at the UN headquarters in New York, marked the third consecutive time that no final document was adopted, raising serious questions about the future of the NPT. US State Department officials criticized the inaction of certain states regarding Iran's noncompliance with its obligations under the NPT and its escalating nuclear activities lacking civilian justification. Conference President Do Hung Viet acknowledged the sincere efforts of delegates but lamented their inability to seize the opportunity to enhance global security. UN disarmament chief Izumi Nakamitsu emphasized the interdependence of non-proliferation and disarmament, urging nuclear-armed states to uphold their commitments. Following the conference's collapse, UN Secretary-General Antonio Guterres warned that the treaty's framework is deteriorating amid urgent global security challenges.
