US Pushes For 3-Way Nuclear Talks With Russia And China As New START Treaty Expires

US official said repeated Russian nuclear violations and weaknesses in New START’s design made it clear that a new framework was needed to address today’s threats.

The United States on Friday called for three-way talks with Russia and China to establish new limits on nuclear weapons, following the expiry of the New START treaty between Washington and Moscow.

Thomas DiNanno, Under Secretary of State for Arms Control, told the UN Conference on Disarmament in Geneva that the treaty, which lapsed on Thursday, had “fundamental flaws".

DiNanno said repeated Russian violations, the growth of global nuclear stockpiles, and weaknesses in New START’s design made it clear that a new framework was needed to address today’s threats. He also criticised China’s nuclear arsenal, saying it currently has “no limits, no transparency, no declarations, [and] no controls".

The under secretary of state for arms control stressed that future arms control efforts must include China alongside Russia to be effective.

New START had limited the US and Russia to deploying 1,550 nuclear warheads each. Its expiration marks the first time in decades that no treaty exists to cap the world’s largest nuclear arsenals, raising concerns of a renewed arms race.

US President Donald Trump rejected a Russian proposal to extend the treaty for another year, calling instead for a “new, improved and modernised treaty".

DiNanno said the United States aimed to strengthen strategic stability and maintain both its own deterrence and commitments to allies. “New START does not allow the United States to credibly uphold both our strategic deterrence commitments to the American people and our extended deterrence commitments to our allies," he said.

China has declined to join negotiations, with Ambassador Shen Jian stating that its nuclear capabilities remain far below those of the US or Russia. “China would not participate in nuclear disarmament negotiations at this stage," he said.

Russia, meanwhile, insists that any new talks must also include other nuclear powers such as France and Britain. Ambassador Gennady Gatilov told the conference that Moscow would only participate if the UK and France, NATO allies of the United States, were also involved.
