UNITED NATIONS – US President Joe Biden said on Monday he is ready to pursue a new nuclear arms deal with Russia and called on Moscow to act in good faith as his Russian counterpart Vladimir Putin said there could be no winners in any nuclear war.

Both leaders issued written statements as diplomats gathered for a month-long UN conference to review the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). It was supposed to have taken place in 2020, but was delayed by the COVID-19 pandemic.

"It occurs at a time of nuclear danger not seen since the height of the Cold War," UN Secretary-General Antonio Guterres told the conference. "Humanity is just one misunderstanding, one miscalculation away from nuclear annihilation."

He warned that crises "with nuclear undertones are festering," citing the Middle East, the Democratic People’s Republic of Korea and the conflict in Ukraine.

Within days of the conflict, Putin put the country's deterrence forces – which include nuclear arms – on high alert, citing what he called aggressive statements by NATO leaders and Western economic sanctions against Moscow.

But in a letter to participants at the NPT review conference, Putin wrote: "There can be no winners in a nuclear war and it should never be unleashed, and we stand for equal and indivisible security for all members of the world community." 

Arms control has traditionally been an area in which global progress has been possible despite wider disagreements. The UN conference takes place five months after the conflict in Ukraine.

Time Washington 'made up its mind'

Moscow and Washington last year extended their New START treaty, which caps the number of strategic nuclear warheads they can deploy and limits the land- and submarine-based missiles and bombers to deliver them, until 2026.

My Administration is ready to expeditiously negotiate a new arms control framework to replace New START when it expires in 2026 … But negotiation requires a willing partner operating in good faith.

"My Administration is ready to expeditiously negotiate a new arms control framework to replace New START when it expires in 2026," Biden said. "But negotiation requires a willing partner operating in good faith."

"Russia should demonstrate that it is ready to resume work on nuclear arms control with the United States," he said.

But Russia's mission to the United Nations questioned if the United States was ready to negotiate, accusing Washington of withdrawing from talks with Moscow on strategic stability over the Ukraine conflict.

"It is high time Washington made up its mind, stopped rushing around, and told us frankly what it is that they want – escalate the situation in the area of international security or embark on equal negotiations," Russia's UN mission said in a statement.

Russia's UN mission

US Secretary of State Antony Blinken told the UN conference that Washington was committed to seeking a comprehensive risk reduction package that would include secure communications channels among nuclear weapon states.

Blinken also said a return to the 2015 nuclear deal remains the best outcome for the United States, Iran and the world.

Japanese Prime Minister Fumio Kishida urged all nuclear states to conduct themselves "responsibly." Kishida is from Hiroshima, which on Aug 6, 1945, became the first city in the world to suffer a nuclear bombing. 

"The world is worried that the threat of the catastrophe of use of nuclear weapons has emerged once again," he told the conference. "It must be said that the path to a world without nuclear weapons has suddenly become even harder."
