特朗普与习近平举行华盛顿峰会 中美同意延长贸易战休战协议Trump and Xi Meet in Washington as US and China Extend Trade Truce

美国总统特朗普于9月23日亲自前往马里兰州安德鲁斯联合基地的停机坪迎接中国国家主席习近平。这是自1962年时任美国总统约翰·肯尼迪迎接英国首相哈罗德·麦克米伦以来，美国总统首次在停机坪以这种方式迎接外国领导人。白宫在东厅举办的国宴同样融入了历史象征元素，开场敬酒选用了世酿伯格黑中白起泡酒，致敬1972年理查德·尼克松与周恩来达成的“和平干杯”，并提及了当年的“乒乓外交”。

US President Donald Trump traveled to the tarmac at Joint Base Andrews in Maryland on September 23 to personally greet Chinese President Xi Jinping. The gesture marked the first time an American president welcomed a foreign leader on the tarmac since John F. Kennedy greeted British Prime Minister Harold Macmillan in 1962. Inside the White House East Room, the state dinner featured historic symbolism, opening with a toast of Schramsberg Blanc de Noirs sparkling wine to honor the 1972 "Toast to Peace" between Richard Nixon and Zhou Enlai, alongside references to "ping-pong diplomacy."

在双边展示外交礼遇的同时，白宫的媒体准入安排引发了外界关注。特朗普一度禁止CNN、MS Now和Politico等媒体的记者进入白宫记者团，导致部分主要电视新闻网未播出峰会画面。尽管该禁令随后被法院推翻，但CNN报道指出，美中双方官员仍对峰会的对外传播效果表达了关切。

Alongside the diplomatic pageantry, media access arrangements during the visit generated friction. Major television news networks did not air the meeting after Trump barred reporters from CNN, MS Now, and Politico from the White House press pool. Although a court subsequently overturned the restriction, CNN reported that officials from both governments voiced concern over how the summit's public image would be received.

在两国元首正式举行会谈前，美国财政部长斯科特·贝森特与中国国务院副总理何立峰进行了会晤，并宣布双方同意将贸易战休战协议再延长两个月。此项关税暂停安排最初于去年10月达成，在此之前双方关税水平曾一度攀升至近150%。

Before the head-of-state summit formally commenced, US Treasury Secretary Scott Bessent met with Chinese Vice Premier He Lifeng and announced an agreement to extend the bilateral trade war truce by an additional two months. The pause on tariff escalations was originally established in October of the prior year, following a period in which bilateral import levies had climbed toward 150 percent on both sides.

此次协议延期正值双边贸易与宏观经济不平衡持续扩大。美国人口普查局数据显示，2026年5月至7月美国货物贸易逆差达3250亿美元，较2025年同期的2770亿美元增长17.4%。与此同时，中国海关数据显示其截至今年8月的货物贸易顺差已达约8200亿美元。在峰会召开前夕，西方经济学家与政策制定者再次呼吁允许人民币升值，指出其估值仍被低估多达30%，但中国决策层因担忧冲击出口企业利润率和国内就业而继续对汇率实施审慎管理。

The extension takes place against a backdrop of persistent macroeconomic trade imbalances. US Census Bureau figures indicate that the American goods trade deficit reached $325 billion between May and July 2026, representing a 17.4 percent increase from $277 billion during the same period in 2025. In contrast, China accumulated a goods trade surplus of approximately $820 billion through August of this year. Ahead of the talks, Western economists and policymakers renewed calls for China to let the yuan appreciate, citing estimates that the currency remains undervalued by up to 30 percent, though Chinese officials have maintained tightly managed exchange rates to shield exporter profit margins and domestic employment.

在白宫国宴上，英伟达首席执行官黄仁勋、AMD首席执行官苏姿丰、苹果执行董事长蒂姆·库克和特斯拉首席执行官埃隆·马斯克与两国元首及夫人同坐主桌。截至周四收盘，这四家公司的总市值超过12万亿美元，四位高管的个人净资产合计超过1万亿美元。在出席国宴的39位美国商界领袖中，科技界人士达15人，占据最大代表群体，其中包括马克·扎克伯格、杰夫·贝索斯以及高通和美光科技的负责人。

At Thursday's White House state dinner, Nvidia CEO Jensen Huang, AMD CEO Lisa Su, Apple Executive Chairman Tim Cook, and Tesla CEO Elon Musk sat at the head table alongside President Trump, First Lady Melania, President Xi, and Peng Liyuan. As of Thursday's market close, the four executives' companies commanded a collective market capitalization exceeding $12 trillion, while the leaders themselves held a combined net worth of over $1 trillion. Technology executives formed the largest contingent among the 39 US business leaders in attendance, with 15 representatives present, including Mark Zuckerberg, Jeff Bezos, Michael Dell, and the heads of Qualcomm and Micron Technology.

半导体巨头与中国市场的复杂交织构成了经贸博弈的重要维度。黄仁勋曾表示，美国出口限制使英伟达几乎完全失去了价值500亿美元的中国人工智能芯片市场；苏姿丰在5月透露，中国市场在AMD总业务中的占比已从2019年的24%降至约20%。与此同时，中国在全球芯片封装测试及稀土等关键原材料供应中扮演核心角色，并在推动技术自立的过程中对重新开放本土芯片市场表现出审慎态度。

The prominent seating highlighted the complex commercial stakes surrounding artificial intelligence and semiconductor hardware. Huang noted that tighter US export controls caused Nvidia to miss out almost entirely on a $50 billion AI chip market in China, while Su indicated in May that China accounted for approximately 20 percent of AMD's total business, down from 24 percent in 2019. China continues to operate as a vital hub for chip packaging and testing, in addition to supplying critical raw materials such as rare earths, even as Beijing pursues technological self-reliance and shows hesitation toward reopening its domestic market to American processors.

在人工智能治理领域，两国领导人探讨了合作管控技术风险的可能途径。新华社通报显示，习近平在会晤中呼吁中美两个全球最大经济体确保人工智能发展始终处于人类控制之下。与此同时，习近平再次就台湾问题寻求美方重申其立场，反映出核心安全议题依然是双边政治互信的关键考量。

Regarding artificial intelligence governance, the two leaders addressed potential avenues for bilateral cooperation to manage emerging technological risks. According to a Xinhua readout of the discussions, President Xi called on the world's two largest economies to ensure that artificial intelligence development remains under human control. Concurrently, Xi sought renewed reassurance from Washington regarding the US position on Taiwan, underscoring that core security questions remain central to bilateral exchanges.

除了双边议题，外部地缘政治冲突与国内政治周期也对两国关系构成现实压力。特朗普目前正面临持续延宕的伊朗战争与国内通胀压力，同时临近11月的中期选举。尽管双方通过高层会晤维持了政治局势的基本稳定，但在中东地缘博弈、高科技竞争与战略安全等深层分歧上，本次华盛顿峰会并未达成具有实质性突破的约束性协议。

Beyond direct bilateral friction, external geopolitical developments and domestic political pressures shaped the context of the summit. President Trump faced ongoing political strains from the protracted war with Iran and domestic inflation ahead of the November midterm elections. While the high-level dialogue maintained a period of diplomatic stabilization between the two powers, the Washington meeting concluded without producing legally binding breakthroughs on deep strategic disagreements involving Middle East conflicts, technological competition, and cross-strait security.
