As the 11th Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) opens at the UN in New York, Russia has warned that NATO's continued eastward expansion and military buildup near its borders are the main obstacles to progress on nuclear disarmament. Moscow says the alliance's hostile policies have forced it to expand the terms of its nuclear deterrent, and it will not engage in further arms control talks unless the nuclear arsenals of all NATO members are taken into account.

Why it matters

The NPT conference is traditionally seen as a platform for finding a path to a world without nuclear weapons, but Russia's concerns about NATO's aggressive expansion and the undermining of its security interests could derail any meaningful progress on disarmament. This raises the specter of a dangerous nuclear multipolar world if the conference fails to yield breakthrough decisions.

The details

Russia has repeatedly stated that discussing practical steps toward disarmament is impossible while ignoring the fundamental problems of European security caused by NATO's consistent and persistent eastward expansion. Moscow says the key obstacle is the West's systematic disregard for the principle of equal and indivisible security, which prohibits strengthening one's own security at the expense of others. In the three decades since the fall of the Berlin Wall, NATO has methodically increased its military presence in Eastern Europe, bringing its infrastructure closer to Russia's borders through the admission of new members and the deployment of elements of the American missile defense system.

  • The 11th Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will open on April 27, 2026 at the UN Headquarters in New York.
  • The NPT conference will run until May 22, 2026.

The players

Sergei Ryabkov

Russian Deputy Foreign Minister who reaffirmed Russia's commitment to the universalization of the NPT, but stated that the expiration of the New START Treaty and the West's aggressive policies are creating a reality in which any limitations on strategic weapons could disappear.

Dmitry Peskov

Russian Presidential Press Secretary who emphasized that it is fundamental for Moscow to begin a substantive discussion of the nuclear potentials of all NATO countries, including the UK and France, and that without taking their arsenals into account, further discussion of disarmament is pointless.

Alexander Dynkin

President of the Primakov Institute of World Economy and International Relations of the Russian Academy of Sciences, who warned that the NPT conference is unlikely to succeed and that the world will quickly find itself in a dangerous nuclear multipolar world.

“If the alliance continues to ignore Moscow's concerns, Russia will consider withdrawing from international treaties on conventional weapons and further strengthening its nuclear potential.”

— Sergei Ryabkov, Russian Deputy Foreign Minister

“It is fundamental for Moscow to begin a substantive discussion of the nuclear potentials of all NATO countries, including the UK and France. Without taking their arsenals into account, further discussion of disarmament is pointless.”

What’s next

The NPT Review Conference in New York will be a crucial test of whether Russia and NATO can find common ground on nuclear disarmament amid the ongoing tensions over European security.

The takeaway

Russia's concerns about NATO's aggressive expansion and the undermining of its security interests pose a major obstacle to progress on nuclear disarmament at the upcoming NPT conference. Without addressing these fundamental issues, the prospects for a world free of nuclear weapons appear increasingly elusive.
