Most important take away

The leverage balance between the US and China has shifted meaningfully in China’s favor over the past year, primarily because of Beijing’s demonstrated willingness to weaponize its grip on rare earths and critical minerals — a chokepoint affecting roughly 4% of US GDP ($1.2 trillion), with about 1.5% having no near-term substitute. Even if the Xi-Trump summit happens, expectations should be modest: soybean purchases, a possible Boeing order, and stability rather than breakthroughs. The one genuine US counter-leverage point now is advanced AI, where Washington still holds a lead Beijing appears quietly worried about.

Summary

Actionable insights and investment angles:

• Rare earths / critical minerals exposure: China continues to collect granular usage data from every importer of its critical minerals, keeping its “Trump card” loaded even while pausing some restrictions. Investors should treat any company with deep rare-earth dependency (autos, defense, semiconductors, clean energy) as carrying tail risk tied to US-China friction. Non-China rare-earth supply names (MP Materials, Lynas, and US government-backed processing initiatives) remain structurally favored, though about 1.5% of US GDP worth of usage has no substitute at all.

• Boeing (BA): A deal for pent-up Chinese demand for Boeing aircraft looks like a likely “deliverable” if the summit goes ahead. This is the clearest stock-specific actionable mention. It also gives China leverage against Airbus (EADSY / Airbus SE) by maintaining two suppliers.

• Soybeans / US ag: China is on the hook to buy ~25 million metric tons by year-end (12M already delivered by February). Timing matters — if orders are back-loaded to late 2026, US farmers and ag-exposed names face cash-flow pressure now. Watch ADM, Bunge, and CF Industries-type exposures for headline sensitivity.

• Semiconductors: H200 shipments to China are essentially stalled; no near-term liberalization on Blackwell or Rubin-class chips. Nvidia (NVDA) China upside from a summit looks limited — the administration’s new appreciation of AI as a strategic weapon argues for tighter, not looser, export controls.

• Chinese EVs / BYD: Despite occasional speculation, US national-security restrictions on Chinese EV and battery investment remain firmly in place. Do not position for a Chinese-EV opening into the US market.

• AI / Anthropic-class capability: The US lead in frontier AI (“Mythos”-type capability referenced) is now viewed inside the administration as a strategic asset worth protecting. This reinforces the bull case for US frontier-AI infrastructure (Nvidia, hyperscalers, leading model labs) and against any thesis that assumes Chinese AI catch-up is imminent.

• Iran / oil and shipping: China has taken the unprecedented step of ordering its companies to ignore US sanctions on private refiners trading Iranian oil. The Strait of Hormuz is the pressure point — disruption risk is elevated, but China wants the strait open. Energy traders should expect headline-driven volatility rather than a structural supply rupture, with both sides incentivized to keep flows moving.

• Sanctions credibility: The episode flags an inflection — the US increasingly has to tolerate non-compliance with its sanctions rather than China hiding behind public defiance. This is a slow-moving negative for the dollar weaponization premise and modestly supportive of gold and non-dollar reserve assets over the medium term.

• Base case for the summit: low ambition, low deliverables, focused on stability through the November truce expiry, APEC, and the 2027 Chinese Party Congress. Position for “muddle through” rather than either a breakthrough rally or a blow-up. The bigger market-moving risk is a last-minute cancellation, which would re-introduce tariff-wall and rare-earth tail risk.

Chapter Summaries

Will the summit actually happen?

Both Welch and Ten Kate lean toward the meeting going forward because it is a low-cost way for both sides to project stability. China is uncomfortable hosting during the Iran war and US sanctions pressure, but canceling risks escalating into a broader rupture before APEC, the G20, and the November tariff-truce expiry.

China’s new sanctions defiance

Beijing ordering Chinese firms to ignore US sanctions on private Iranian-oil refiners is a meaningful escalation versus past practice, where state banks quietly complied to retain dollar access. China is now confident enough in its rare-earth leverage to dare Washington to sanction its banks.

The leverage shift

China’s 2025 demonstration of critical-minerals leverage materially altered policymaking in Washington. Bloomberg Economics research cited puts 4% of US GDP ($1.2T) as rare-earth exposed, with 1.5% non-substitutable. This shadow is restraining US action across export controls, defense strategy, and Taiwan arms sales.

Trade deliverables if the summit happens

Expect modest wins: Boeing aircraft orders, partial soybean purchase fulfillment, and clarity on where the rebuilt tariff wall settles. Don’t expect advanced-chip liberalization or a Chinese mega-investment package in the US. National-security restrictions remain binding on both EVs and frontier semis.

AI as US counter-leverage

The US still leads on potent frontier AI tools, and Beijing has been conspicuously silent on the topic — read as concern. The administration’s posture has shifted from “share advanced chips” to “press the advantage,” strengthening the case for sustained or tightened export controls.

Iran as collateral damage in US-China relations

Trump’s Iran priorities (blockade, refiner sanctions) were taken without weighing the China impact, creating friction points heading into the summit. China is responding with blocking rules and by hosting Iran’s foreign minister in Beijing just before the meeting.

Xi’s domestic context and the optics

With a 2027 Party Congress approaching and Xi having purged top generals, internal turbulence makes a stable external environment valuable. Watch the optics — red carpet, smiles, Taiwan language, joint-statement tone — rather than headline deliverables, for the real read on the relationship.
