Trump plans to meet Putin and Xi together in China to discuss cutting nuclear weapons

Fact-check index: 70/100 — Core claims about the Trump-Putin-Xi trilateral meeting in China and nuclear weapons discussion are directly supported by the BBC source, but the Iran war agenda item and the framing of it as the first trilateral meeting among the three largest nuclear powers are not clearly established in the provided material.

• Trump will meet Putin and Xi together in China next week, per White House/BBC — Directly matches BBC headline and article: 'Trump, Putin and Xi plan historic joint meeting in China next week, White House says.'
• Trump will discuss 'reduction of nuclear weapons' during the talks, per a White House spokeswoman — BBC subheadline states verbatim: 'Trump will discuss the "reduction of nuclear weapons" during the unprecedented talks, a spokeswoman says.'
• The war in Iran is also expected on the agenda, per voz.us — The voz.us headline mentions 'the war with Iran' as a discussion topic, but only the headline is given in source material (no body text), so this is weakly sourced to a single aggregated headline rather than a verified detailed account.
• It would be the first trilateral meeting among the leaders of the world's three largest nuclear powers — Multiple headlines call it the 'first-ever trilateral meeting,' supporting the novelty claim, but none of the provided source snippets explicitly characterize the three countries as 'the world's three largest nuclear powers' — this specific framing is not directly verified in the material.
• Any arms-control understanding reached could reset norms anchoring nuclear diplomacy for decades (Why it matters) — This is analytical commentary/framing added by the article, not attributed to or found in any of the cited source snippets.
• Whether the summit yields concrete commitments or only a framework for further talks (What to watch) — Speculative framing not found in the source material; the Benzinga headline suggests the White House does not expect major outcomes, but this specific framing is the article's own addition, not sourced.
