Chips Out, Magnets In: Why Xi Is Coming to Washington

A dinner table with the whole AI boom on it

Xi Jinping lands in Washington on Wednesday for a Thursday summit with Donald Trump, the first state visit by a Chinese leader in 11 years ¹. The reported guest list for Thursday's East Room dinner is the story in one line: Elon Musk, Sam Altman, Tim Cook, Jeff Bezos, Jensen Huang and Sundar Pichai, alongside a Chinese trade delegation ². The owners of the models, the clouds, the devices and the silicon, dining with the state that processes about 90 percent of the world's rare earths ³.

Both men need a truce more than a deal

Why Xi is here: the trade truce struck in late 2025 expires in November, and whether the leaders signal an extension is the summit's main business ⁴.

Xi arrives strong. China's global trade surplus is pacing above $1 trillion for a second straight year, more than half of the roughly 6,500 product categories China sells into the US have grown since 2025, and the 2025 US trade deficit with China was $202.1 billion ⁴⁵. "Xi is not really looking for anything tangible," said Jon Czin, a Brookings analyst and former National Security Council China director. "He wants to extend the gentleman's agreement with Trump so that China has time to fortify itself" ⁴.

Trump, less than six weeks from midterms and at the lowest approval rating of his career, wants countable wins: Boeing orders and farm purchases ¹⁴. Treasury Secretary Scott Bessent called preparatory New York talks with Vice Premier He Lifeng on AI guardrails and non-sensitive goods "very successful," and a framework cutting tariffs on roughly $30 billion of trade is in play ⁴².

Chips go east, magnets come west

In late August, Trump opened a licensed path for Nvidia's H200 to reach approved Chinese buyers, with Washington taking 25 percent of the sales revenue ⁶. ByteDance and Tencent have reportedly taken about 10,000 chips each, against reported demand potential of up to a million, while Blackwell and Rubin stay restricted and Beijing must still approve each purchase ⁶.

The minerals run the other way. China's rare-earth magnet exports to the US fell 21 percent↗ in August to 512 tons, and are averaging about 504 tons a month this year against 621 in 2024, before Beijing imposed controls in April 2025 ⁷. China hopes to offer more generous export licenses as a bargaining chip, people familiar with the matter said ⁷.

Peace, in this corner of the market, is a selloff

US rare earth equities price Chinese scarcity, so a thaw removes part of the reason to pay a premium for a Western substitute ⁸. On 4 September, MP Materials rose 4 percent↗ on reports Chinese suppliers were refusing US shipments ⁹. On 10 September, thaw headlines knocked MP down 5 percent↗ and USA Rare Earth 4 percent while the S&P 500 slipped half a percent ⁸.

On 14 September, Beijing's threat to cancel the summit over an unsigned $14 billion Taiwan arms package took between 0.8 and nearly 2 percent off the group ³. The business underneath is real: MP's second-quarter revenue rose 89 percent to $108.5 million, and USA Rare Earth just broke ground on a $1.2 billion South Carolina magnet plant ⁸.

The ratchet a dinner cannot unwind

Chinese equities have drifted up into the visit, with the large-cap China ETFs FXI and MCHI each gaining about 1.5 percent ¹⁰. A truce extension lifts ADRs the way it lifts everything else, by removing the November cliff. What it cannot fix is the security ratchet: the FCC's covered list, the Pentagon's 1260H roster and the Entity List's 50 percent ownership rule keep expanding regardless of the toasts, and a former senior FCC lawyer argues the era of automatic access to the American market is already over ¹¹.

Watch the arms package, not the toasts

Three tells. Whether a truce extension is announced before November ⁴. Whether H200 licenses ship at scale, which needs Beijing's sign-off purchase by purchase ⁶. And whether Trump signs the Taiwan arms package Congress authorized in January, the tripwire Beijing named for walking out ³. The rare earth tickers will read the outcome faster than any communique.
