President Trump told reporters that US-China AI cooperation was only “big talk” — hours later, Beijing announced a 30% tariff cut on 134 American product categories and pledged AI dialogue expansion at the summit. The reversal stunned markets and left analysts scrambling to reconcile the tough rhetoric with the sudden concession.
The tariff reduction targets key US exports including farm products, aircraft components, and auto parts, reducing rates from 15-45% to 5-15%. White House economic adviser Kevin Hassett confirmed the deal framework, saying Beijing agreed to remove retaliatory tariffs on US soybeans and LNG shipments that had been in place since April 2025.
Trump’s previous Xi summit in June 2025 had already addressed rare earth supply chains, but this round added semiconductor export controls to the agenda. The US agreed to ease restrictions on advanced chip equipment sales to Chinese firms, while China committed to purchasing additional American agricultural products worth $12 billion over the next 12 months.
The AI cooperation component remains vague. Both sides agreed to establish a joint working group on artificial intelligence safety standards, though no specific commitments on technology transfer or data sharing were announced. China’s state media described the outcome as “constructive,” while US officials framed it as a first step rather than a comprehensive deal.
US equity markets responded immediately. The Dow Jones Industrial Average rose 1.8% in afternoon trading, with technology stocks leading gains. NVIDIA, Apple, and Microsoft each added between 2-3% as investors priced in reduced geopolitical risk to semiconductor supply chains. The tariff cuts on US farm exports provided additional relief to agricultural states that had been hit hardest by the trade war.
Trump’s rejection of Iran’s ceasefire proposal hours before the Xi meeting added complexity to the diplomatic picture. The White House signal of firmness on Tehran appeared designed to strengthen Trump’s negotiating position with Beijing, suggesting the US was willing to maintain pressure on multiple fronts simultaneously.
China’s Ministry of Commerce confirmed the tariff adjustments on its official website, stating that “mutually beneficial cooperation” would replace confrontation. The Chinese MFA spokesperson urged both sides to “respect each other’s core interests” and said the working group would meet within 30 days to establish AI safety protocols.
The $30 billion in combined tariff reductions represents the largest single trade concession between the two economies since the 2018-2019 trade war. US Treasury Secretary Scott Bessent called the deal “a real breakthrough” but cautioned that implementation details still need to be worked out.
Environmental groups raised concerns about the agricultural purchase commitment, noting that expanded farming could increase fertilizer runoff into the Mississippi River basin. The deal’s climate implications remain unaddressed in joint statements, though both sides agreed to revisit the topic at the next ministerial meeting.
Existing US tariff frameworks on Russian energy provided a template for enforcement mechanisms, though the China deal includes weaker verification provisions. Critics noted that the 12-month agricultural purchase commitment lacks binding penalties for non-delivery.
The joint AI working group announcement marks the first time the two superpowers have formally agreed to cooperate on artificial intelligence governance. Industry analysts say this could reshape global technology standards, though the absence of specific deliverables leaves room for skepticism.
