Washington on Monday accusedChinaof dramatically swelling its nuclear arsenal, and doubled down on claims that Beijing has conducted secret nuclear tests, demanding again it be part of any future arms control treaty.

Washington said the lapsing earlier this month of New START — the last treaty between top nuclear powers the United States and Russia — presented the possibility to achieve a “better agreement” including Beijing.

China has publicly rejected calls to enter negotiations on a new three-way treaty.

Christopher Yeaw, the US assistant secretary of state for arms control and nonproliferation, told the Conference on Disarmament in Geneva that New START had been seriously flawed and “did not account for the unprecedented, deliberate, rapid and opaque nuclear weapons build-up by China”.

“Despite its claims to the contrary, China has deliberately and without constraint, massively expanded its nuclear arsenal without transparency or any indication of China’s intent or end point,” he charged.

He added that US government officials “believe China may achieve parity within the next four or five years”, without elaborating on what he meant by parity.

Both Russia and the United States have more than 5,000 nuclear weapons, according to the Nobel Peace Prize-winning campaign group ICAN.

But New START, which expired on February 5, restricted the United States and Russia to 1,550 deployed nuclear warheads each — a number Washington says China is fast approaching.

“Beijing is on track to have the fissile material necessary for more than 1,000 nuclear warheads by 2030,” Yeaw said.

The expiration of New START marks the first time in decades that there is no treaty to curtail the positioning of the planet’s most destructive weapons, sparking fears of a fresh arms race.
