Chinese President Xi Jinping’s first US state visit in 11 years to Washington produced a two-month extension of the trade truce to January 10, 2027, and agreements on an AI dialogue channel and $30 billion in tariff reductions. However, no breakthroughs were reached on Taiwan, where Xi urged the US to oppose independence, or on technology competition, rare earths, and geopolitical issues like Iran and North Korea. The summit was heavy on pageantry but light on substance.
