Donald Trump will participate in the first-ever trilateral meeting between the leaders of the U.S., China and Russia on the sidelines at the Asia-Pacific Economic Cooperation (APEC) Summit in China next week, senior U.S. officials told reporters Friday evening.

Trump is expected to discuss Iran with Chinese President Xi Jinping and Russian President Vladimir Putin, the officials said, but he does not intend to discuss Russia’s war with Ukraine during the trilateral meeting.

Denuclearization will be the focus of the long-awaited trilateral meeting, though officials do not anticipate the leaders reaching any concrete agreement and are characterizing this meeting as an initial conversation broaching the subject.
