Putin Notifies Xi Of New START Status As Trump Ready To Let Go Of Nuclear Arms Control With Russia

President Putin in his Wednesday video call with Chinese President Xi Jinping underscored that the last major nuclear treaty with the United States is on the eve of collapse.

New START is set to expire on Thursday. Putin notified Xi that Washington has not yet responded. ”As you know, on September 22, 2025, we proposed to the Americans to extend the key quantitative limits for one year as voluntary self-restrictions. However, we have not yet received an official response from the Americans,” Putin said, as quoted in state media.

Despite the situation with the New START Treaty, Russia remains open “to seeking negotiated ways to ensure strategic stability” – the Russian leader explained.

Putin further stated his country will act “in a measured and responsible manner, based on a thorough analysis of the overall security situation.”

Over several years going back to his first term, Trump has signaled a desire to forge a broader deal which would bring China into the agreement, which hearkens back to the Obama administration. 

Politico is meanwhile reporting that the Trump administration is preparing to “let go of arms control with Russia”:

The likely dissolution of the agreement comes at an especially fraught time. Russia and China are expanding their strategic arsenals and the Kremlin has threatened to use nuclear weapons on Ukraine. The Defense Department has held a series of internal meetings in preparation for a post-New START world, according to the two people and another person familiar — all of whom were granted anonymity to discuss internal talks — although it’s not clear what was discussed in the meetings.

“We’re looking at a very uncertain path ahead,” said Daryl Kimball, the executive director of the Arms Control Association. “Unless Trump and Putin reach some sort of understanding soon, it’s not unlikely that Russia and the U.S. will start to upload more warheads on their missiles.”

The Kremlin has made clear Russia is willing to extend it for another year, to allow more robust negotiations and for a longer deal to be finalized. But again, unless it is renewed or extended at the last minute, the landmark treaty will expire on Thursday, February 5.

Former Russian president Dmitry Medvedev, now deputy chairman of the country’s Security Council, on Monday made clear that Russia’s offer to quickly extend “remains on the table, and the treaty has not even expired yet, and if the American side wants to extend it, then this can be done.”

He also confirmed that Moscow has received no response on this offer from Washington:

Medvedev told the newspaper Kommersant that Moscow might have to wait until the expiry of the treaty on February 5 for a U.S. response to the Russian initiative.

When contacted for comment, a White House official told Newsweek Monday: “The president will decide the path forward on nuclear arms control, which he will clarify on his own timeline.”  

Indeed, the Trump White House has yet to issue anything official. Of course, President Trump is also known for making key decisions at the last moment, building suspense and leverage, based on also on his notorious unpredictable decision-making style.

The New START treaty, which has contained the risk of a nuclear standoff between America and Russia, expires soon. To make matters more dangerous, there is a new player in the game—China: https://t.co/w2LZ59AbYu pic.twitter.com/xNySz54I0V

According to Monica Duffy Toft, professor of international politics and director of the Center for Strategic Studies at The Fletcher School, “By providing transparency into the world’s two largest nuclear arsenals, New START has lowered the risk that either side will misinterpret normal military activity as preparation for a nuclear strike.”

It was signed in 2010 by Presidents Barack Obama and Dmitry Medvedev, and limits the number of deployed strategic warheads to 1,550 per side, and caps deployed delivery systems – including of missiles, bombers, and submarines – at 700. There’s also a mutual inspection regimen, allowing each side to monitor the other’s sites.
