US-China Step Up Diplomatic Engagement Ahead of Xi-Trump Summit

Beijing and Washington are intensifying diplomatic engagement ahead of the expected September 24 summit between Chinese President Xi Jinping and US President Donald Trump, with Foreign Minister Wang Yi and US Secretary of State Marco Rubio discussing preparations for high-level exchanges and key international issues. Their talks come as both sides seek to keep ties on a stable track despite persistent disagreements over trade, Taiwan, technology and the Middle East.

Xi is expected to arrive in the United States on September 23, with reports saying Trump plans to personally receive him on the tarmac at Joint Base Andrews. The summit would mark the leaders’ second face-to-face meeting this year, following Trump’s visit to Beijing in May. Beijing, however, has yet to formally confirm the September 24 date.

Wang has described head-of-state diplomacy as the “stabilising anchor” of China-US relations and called for equality, mutual respect and mutual benefit. He urged both sides to strengthen communication, advance cooperation, manage differences and respect each other’s core interests. The latest Wang-Rubio conversation also covered the Middle East, shortly after Wang met Iranian Foreign Minister Abbas Araghchi in Beijing.

The summit comes against the backdrop of a relationship transformed by the 2018 US-China trade war into a wider strategic competition involving technology, supply chains and national security. A tariff truce reached after the October 2025 Trump-Xi meeting is due to expire on November 10, making its extension a major issue. US officials are also seeking progress on agriculture, market access and non-tariff barriers.

The May 2026 Xi-Trump meeting in Beijing produced several economic understandings. China agreed to address US concerns over critical-mineral supplies, approved an initial purchase of 200 Boeing aircraft and committed to buying at least $17 billion annually in US agricultural products in 2026, 2027 and 2028.

Rare earths and critical minerals remain important bargaining issues because of China’s dominant role in processing several strategic materials. At the same time, Washington’s restrictions on advanced semiconductors and Beijing’s push for technological self-reliance have made technology a central component of the rivalry.

Taiwan remains the most sensitive security issue, with Beijing seeking stronger US opposition to Taiwanese independence. A pending US arms package for Taiwan reportedly worth up to $14 billion adds another point of tension.

Artificial intelligence is emerging as another strategic frontier, although both sides have shown interest in discussing shared AI risks. Fentanyl precursor chemicals and law-enforcement cooperation offer a narrower area for practical engagement.

The Middle East is also entering the diplomatic agenda. Wang’s talks with Rubio followed his meeting with Iran’s foreign minister, where he called for restraint, substantive consultations and the reopening of the Strait of Hormuz.

With trade, technology, Taiwan, critical minerals, Iran and military communication all interconnected, the September summit will test whether Xi and Trump can translate their leader-level engagement into concrete arrangements for managing competition and preventing further escalation in US-China relations.
