Donald Trump, Vladimir Putin and Xi Jinping are planning to meet on the sidelines of a summit in China next week, the White House has said.

The historic meeting between the leaders of the US, Russia and China will take place as Trump attends the Asia-Pacific Economic Cooperation (Apec) summit in the southern city of Shenzhen, spokeswoman Olivia Wales told reporters.

“The president has made it clear that, among other topics, he will discuss the reduction of nuclear weapons in the world, whose proliferation President Trump believes is very dangerous,” she said.

It is understood Iran may also be discussed during the meeting of the world’s biggest nuclear powers, but not Ukraine. Moscow and Beijing are yet to comment.

No agreement was expected to follow the talks, an unnamed, senior American official said, according to news agencies AP and Reuters.

Trump will arrive in Shenzhen late on Wednesday for the two-day summit between the 21 member states. He will also take part in bilateral talks with Xi on Thursday – their fourth meeting since the US president returned to office in 2025.

“President Trump will conclude his visit to China with a trilateral meeting between the president of the United States, the president of the People’s Republic of China, and the president of the Russian Federation,” Wales said.

She said Trump’s trip, which will also include attending an Association of Southeast Asian Nations (Asean) summit in the Philippines on Tuesday, would “secure historic wins to the American people and advance America’s interests in the Indo Pacific”.

A nuclear weapons control treaty between the US and Russia expired in February, leaving the world’s biggest nuclear arsenals without major guardrails and effectively marking an end to the arms control co-operation which helped to resolve the Cold War.

The UN has urged both sides to agree a new framework without delay. Trump however said he could replace the deal with a better agreement which included China, which has been building up its arsenal.

Former senior US officials and analysts told the BBC at the time that seeking Beijing and Moscow’s co-operation could turn up major hurdles and take years.
