WASHINGTON: Donald Trump, Vladimir Putin and Xi Jinping will hold the first ever three-way meeting between the leaders of the United States, Russia and China at a summit in Shenzhen next week, the White House said Friday.

Trump wants to talk about reducing nuclear arsenals at the trilateral talks on Thursday and is also set to bring up his war in Iran – but he is not expected to discuss Russia's war in Ukraine, US officials said.

The three leaders will meet on the sidelines of the Asia-Pacific Economic Cooperation summit in the southern Chinese city, White House 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. This proliferation, President Trump believes, is very dangerous," Wales said.
