The White House said the arrangement is part of efforts to operationalise the Board of Trade, which was established during the May 2026 Trump-Xi summit.For US exports to China, the products identified include agricultural goods, fish and seafood, logs and wood products, cosmetics and medical devices. In the other direction, products covered include consumer items such as small appliances, toys, holiday decorations and children’s car seats.China’s Ministry of Foreign Affairs separately said the two countries had reached an agreement on “ billion” in reciprocal tariff reductions and would continue implementing the outcomes of their earlier economic and trade consultations.The arrangement does not represent the removal of all US-China tariffs. Instead, it focuses on a defined group of non-sensitive goods while the two governments continue negotiations on broader economic issues.US and China Agree on AI Communication ChannelTrade was not the only major area discussed during Xi’s visit. The US and China also agreed to establish a bilateral dialogue on artificial intelligence, with the next exchange scheduled by November 2026.The White House said the two countries would use the dialogue to discuss the risks and benefits associated with what it calls “super intelligence”. Both sides also agreed to create a communication channel for incidents involving these technologies.The agreement follows discussions between US Treasury Secretary Scott Bessent and Chinese Vice Premier He Lifeng over AI safety and emergency communication. Earlier reporting said the US had proposed a mechanism for notifying the other side about significant AI incidents.Xi Jinping’s US VisitXi Jinping’s visit to the US took place from September 23 to 25 and included meetings with Donald Trump at the White House. The two leaders discussed trade, artificial intelligence and wider international issues.The Chinese Foreign Ministry said the leaders agreed to build a “constructive relationship of strategic stability” based on respect, fairness and reciprocity. Beijing also said the two countries agreed to continue using economic and trade mechanisms, including the Trade Council, to carry forward the outcomes of their negotiations.The White House said the visit also resulted in the operationalisation of both the US-China Board of Trade and the Board of Investment.Why Did the US and China Impose Tariffs?The latest arrangement comes after years of trade tensions between the world’s two largest economies.The US began imposing major tariffs on Chinese imports in 2018, citing concerns over Chinese trade practices, intellectual property and the large US trade deficit with China. The tariff dispute expanded during subsequent years, with Washington and Beijing imposing duties on products from each other.China responded with its own tariffs on US exports and introduced additional trade measures, including restrictions affecting certain critical minerals and US entities. The escalation continued into the first half of the 2020s before the two sides began negotiating tariff reductions and temporary arrangements.Reuters reported that the US-China trade relationship moved through several rounds of tariff increases, negotiated pauses and temporary truces before the latest 2026 discussions.What Happens Next?The latest arrangement creates formal channels for continued discussions rather than ending the wider US-China trade dispute. The Board of Trade will continue working on market-access issues, including agriculture, while the Board of Investment will provide another mechanism for discussing investment-related concerns.The AI dialogue is also expected to continue, with the next exchange due by November 2026. The two governments have said the communication channel is intended to help address incidents involving advanced AI systems.
