Trump, Xi and Putin to meet in China next week

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 in China next week, the White House has announced.

Mr Trump wants to talk about reducing nuclear arsenals at the trilateral talks on Thursday and is also set to bring up the war in Iran.

However, he is not expected to discuss Russia's war with 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," Ms Wales said.

One of the major conflicts dominating Mr Trump's second term as president will feature, but the other will not, the US officials said.

"I think the president does intend to talk about Iran in the trilateral meeting with Xi Jinping and Vladimir Putin," a senior US official, speaking on condition of anonymity, told reporters.

Washington has a "whole other track" of negotiations with Kyiv and Moscow aimed at ending the war in Ukraine, the official added, referring to talks that US envoys have had in recent days with Mr Putin and Ukrainian President Volodymyr Zelensky.

"China is not really a part of that track, so it doesn't seem appropriate to have the Ukraine discussion there," the official added.

The US president is also not expected to meet with North Korean leader Kim Jong Un during his trip to Asia, according to the officials.

Tesla and SpaceX boss Elon Musk will accompany Mr Trump on his trip to China but won't be involved in the meeting the officials said.

Mr Trump will also hold a working lunch followed by a meeting with the Chinese president on Thursday, their fourth meeting since the US president returned to office last year.

Mr Trump is not scheduled to have a separate one-on-one with the Russian leader.

Among other topics, Nvidia CEO Jensen Huang's resignation over an affair with an alleged Chinese spy is not expected to come up in Mr Trump's meetings with President Xi, the officials said.

The United States also did not plan to discuss export controls on sensitive chip technology, which were at the heart of an investigation involving Mr Huang's relationships.

"We do not negotiate American export controls. These are national security matters that we develop in the administration... and we don't expect it to figure at all in any of our conversations with the Chinese while we're there," officials said.

Mr Trump will leave Washington on Monday and arrive in the Philippines on Tuesday for the Association of Southeast Asian Nations summit before heading to Shenzhen.
