Tokayev Calls for Nuclear Talks 35 Years After Semipalatinsk Closure
President Kassym-Jomart Tokayev has called for negotiations among nuclear powers and urged faster action to bring the Comprehensive Nuclear-Test-Ban Treaty, designed to prohibit all nuclear test explosions, into force as Kazakhstan marked the 35th anniversary of the closure of the Semipalatinsk nuclear test site on August 29. The date also marks the International Day against Nuclear Tests, established by the UN General Assembly at Kazakhstan’s initiative in 2009. “Our country’s position as one of the leaders of the global anti-nuclear movement remains unchanged. We call for negotiations among nuclear powers, the earliest possible entry into force of the Comprehensive Nuclear-Test-Ban Treaty, and decisive multilateral action to eliminate the threat of nuclear weapons use,” Tokayev said. He said Kazakhstan’s decision to relinquish the world’s fourth-largest inherited nuclear arsenal reflected a choice in favor of peace, security, and sustainable development. Tokayev also said nuclear energy should be used exclusively for peaceful purposes, linking the country’s referendum-backed development of nuclear power to its long-term economic, scientific, and technological development. A Call After New START’s Expiry New START, the last U.S.-Russian strategic nuclear arms treaty, expired on February 5, 2026. On-site inspections, paused by mutual agreement in March 2020 because of the pandemic, never resumed. Russia blocked inspections in 2022 and halted treaty-required data exchanges after suspending implementation in 2023. The treaty’s expiry removed the last legally binding bilateral limits on deployed U.S. and Russian strategic nuclear forces, with no successor agreement in place. The Comprehensive Nuclear-Test-Ban Treaty has still not entered into force nearly three decades after opening for signature. It has been signed by 188 states and ratified by 179. Ratification by nine of the 44 states whose ratification is required for the treaty to enter into force is still needed. China, Egypt, Iran, Israel, and the United States have signed but not ratified. India, North Korea, and Pakistan have not signed, while Russia revoked its ratification in 2023. Speaking at a Stimson Center event in Washington on August 26, co-hosted by the Tony Blair Institute for Global Change and attended by The Times of Central Asia, International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi made a broader case for renewed engagement. “This is an era for diplomacy,” Grossi said, arguing that growing international fragmentation has made diplomacy more necessary. Tokayev also brings direct experience to the issue. Before becoming president, he served as a UN under-secretary-general and director-general of the UN Office at Geneva, the UN secretary-general’s personal representative to the Conference on Disarmament, and secretary-general of the Conference on Disarmament. Disarmament in Practice The Soviet Union conducted 456 nuclear tests at Semipalatinsk between 1949 and 1989, causing lasting damage to human health and the environment in surrounding regions. After independence, Kazakhstan transferred the nuclear warheads on its territory to Russia, joined the Nuclear Non-Proliferation Treaty as a non-nuclear-weapon state, and worked with the United States to dismantle associated infrastructure under the Cooperative Threat Reduction program. Much of that cooperation took place through the program commonly known as Nunn–Lugar....
