United Nations Secretary-General Antonio Guterres warned on Wednesday that the expiration of New START, the U.S.-Russia nuclear arms reduction treaty, marks a grave moment for international peace and security, calling on the two countries to return to the negotiation table.
"For the first time in more than half a century, we face a world without any binding limits on the strategic nuclear arsenals of the Russian Federation and the United States of America, the two states that possess the overwhelming majority of the global stockpile of nuclear weapons," Guterres said in a statement.
New START, which limits the number of deployed nuclear warheads and strategic delivery systems of Russia and the United States, expires on Thursday.
Throughout the Cold War and its aftermath, nuclear arms control between the two countries helped prevent catastrophe. It built stability and, when combined with other measures, prevented devastating miscalculations. Most importantly, it facilitated the reduction of thousands of nuclear weapons from national arsenals. Strategic arms control drastically improved the security of all people, not least the populations of the United States and Russia, said Guterres.
This expiration of New START could not come at a worse time, as the risk of a nuclear weapon being used is the highest in decades, he said.
"Yet at this moment of uncertainty, we must search for hope. This is an opportunity to reset and create an arms control regime fit for a rapidly evolving context," the statement said. "I welcome that the presidents of both states have made clear that they appreciate the destabilizing impact of a nuclear arms race and the need to prevent the return to a world of unchecked nuclear proliferation. The world now looks to the Russian Federation and the United States to translate worlds into action."
The secretary-general urged the two states to return to the negotiation table without delay and agree on a successor framework that restores verifiable limits, reduces risks and strengthens common global security.
New START, which entered into force in 2011, was the last arms control pact between Russia and the United States after Washington withdrew from the Intermediate-Range Nuclear Forces Treaty in 2019.

South China's Guangdong Province is accelerating its transformation into an international medical tourism hub, positioning itself as a destination for patients worldwide seeking affordable, high-quality care.
The push follows a joint initiative announced in late March by nine Chinese government departments, including the Ministry of Commerce, aimed at boosting spending by foreign tourists and enhancing exports of tourism services as part of broader efforts to expand the country's service sector.
Every day, some of the most complex surgeries are performed here. Li Zilun, deputy director of the division of vascular surgery at the First Affiliated Hospital of Sun Yat‑sen University, is among the doctors capable of carrying out these intricate procedures.
He recently completed surgery on a patient with an aortic aneurysm, a condition often described as a "time bomb" in the body’s main artery, increasingly common in aging societies around the globe. Li also specializes in highly difficult and pioneering procedures, including repairing leaks caused by failed grafts.
"This was a very challenging case. And then, we implanted the covered stent to eliminate the endoleak. Actually, the outcome was pretty good. The patient will be discharged today," said Li Zilun.
The ability to handle such complex cases -- combining international techniques with domestically produced devices -- is drawing patients from around the world to seek treatment. In addition, high safety standards and low costs are also major draws.
"Our government is encouraging innovation. So, lots of physicians -- including our vascular surgeons -- we are actively involved in the innovation that helps to increase the effectiveness and safety, and also bring down the cost," said Li.
This hospital is one of the first in Guangdong to be designated by the provincial health commission as a pilot site for building an international medical service hub.
The growing number of patients has pushed the hospital to explore new ways to transform every step -- from treatment to payment and everything in between -- into a seamless experience, reducing waiting times and delivering better care for patients.
"I think it's fast. When the patient come here for just about, I think, one week, you can solve the problem," said Xiao Haipeng, president of the First Affiliated Hospital of Sun Yat-sen University.
The hospital is also deepening its international cooperation with top-tier medical institutions, including those at Harvard University.
"Not just for China, for the whole globe, we are facing health care challenges -- emerging infectious disease and chronic, lung infectious diseases, and also the aging population, also the shortage of healthcare workforce," said Xiao.
In response to these challenges, China is promoting its own solutions, including aggressive innovation in artificial intelligence (AI)-driven workflows, while stepping up research and development investment and global engagement along the way.
"In recent years, the innovation in Western medicine is dramatically growing. An example of my hospital -- in the past few years, we have 140 innovations and seven of them are international leading innovations," said Xiao.
As global demand for medical tourism grows, China is positioning itself as a new destination. Official data shows that the number of foreign patients in Guangdong increased by 20 percent last year. Among them, the growth in inpatient admissions was even faster, rising by 76 percent.
