Xi's Washington visit yields diplomacy over deals as markets digest uncertainty

Xi Jinping arrived in Washington to the full ceremonial treatment—state dinner, marching band, the works—and departed days later having produced something considerably less grand than the pageantry suggested. The U.S. and China announced a tariff reduction on thirty billion dollars' worth of goods, with American agricultural products, wood, and cosmetics heading to China, while small appliances, toys, and decorations would see lower duties coming the other way. They also committed to launching a dialogue on artificial intelligence. On paper, movement. In practice, the agreement stopped short of any binding purchase commitments, and the two-month extension of their trade truce fell well short of the six-month duration analysts had anticipated before the summit.

Peter Alexander, a Shanghai-based managing director at Z-Ben Advisors, captured the underlying reality plainly: the two countries remain locked in what he called a fraught relationship where neither side is prepared to yield ground, at least not yet. The visit produced personal diplomacy—the kind that keeps channels open and prevents things from deteriorating further—but not the kind that reshapes the competitive landscape between the world's two largest economies.

Meanwhile, the Middle East remained a source of acute uncertainty. Xi and President Trump agreed that Iran should honor its commitment to forgo nuclear weapons development and that no country should impose transit tolls on international waterways. But Iran's foreign minister, Abbas Araghchi, was simultaneously playing a different game. On NBC's "Meet the Press" that Sunday, he declared Tehran ready for a "doomsday" confrontation with the United States while insisting the country remained open to diplomacy and unwilling to "miss any chance for peace." Days earlier, Araghchi had proposed reopening the Strait of Hormuz and resuming nuclear negotiations within a week if Washington accepted Tehran's conditions. The two nations have been engaged in an on-and-off conflict since late February, a standoff that has constrained global oil supplies and kept upward pressure on inflation.

The tensions took on a tangible edge when British police arrested five men on Sunday near a U.S. air base in the UK, acting on intelligence that three vans were heading toward the facility. The men faced suspicion of terrorism and explosives offenses. Trump's rejection of Iran's ceasefire conditions sent oil markets higher: Brent crude rose 1.9 percent to $106.31 a barrel, while West Texas Intermediate gained 1.3 percent to $93.63.

For investors, the week ahead carried multiple layers of complexity. Treasury yields had climbed to their highest levels since 2007, a shift that would make the already historic buildout of artificial intelligence infrastructure considerably more expensive to finance. Yet there were small signs of thaw in the U.S.-China relationship. The Information reported that Beijing had signaled willingness to allow domestic firms—ByteDance and Alibaba among them—to purchase Nvidia's RTX PRO 5500 chips, designed for high-end professional computing. China's Ministry of Industry and Information Technology had asked these companies to report their purchase intentions, a modest but notable opening after the summit.

The diplomatic calendar continued to fill. Dario Amodei, CEO of Anthropic, had missed Thursday's state dinner due to a scheduling conflict but would join Trump for a private White House dinner on Sunday—their first one-on-one meeting. The Thursday dinner had hosted Sam Altman of OpenAI, Elon Musk of SpaceX, Jensen Huang of Nvidia, and Mark Zuckerberg of Meta, alongside officials from both governments. China, for its part, was preparing to report industrial profits for the first eight months of the year, with manufacturers continuing to face headwinds from elevated commodity costs and weak domestic demand. The week ahead would test whether the diplomatic gestures from Washington could translate into something more durable than ceremony.
