Can a first three-way summit between Trump, Xi and Putin produce a nuclear deal?

The White House says Trump, Xi and Putin will meet on Thursday on the sidelines of the APEC summit in Shenzhen, China, the first time the three sit down together. Moscow and Beijing have not yet commented on the meeting. Trump stops in Manila first.

The White House says the agenda centres on nuclear arms. Spokeswoman Olivia Wales said: 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.

China holds more than 600 warheads, and US officials say it is on track for a thousand by the end of the decade. The New START treaty between Washington and Moscow expired in February. Officials say no deal is expected from this first meeting, only a starting point.
