The Busan Handshake: How China's Rare Earth Chokehold Rewrote the Trade War Playbook

A 105-minute meeting in South Korea revealed which superpower holds the cards in the new era of economic warfare

BUSAN, South Korea — When Donald Trump arrived early at an air base on the edge of this coastal city and walked Xi Jinping to his car after their closed-door meeting, Chinese commentators saw something American analysts might have missed: the optics of deference masking a strategic retreat.

The October meeting between the U.S. and Chinese presidents, which stretched 45 minutes beyond schedule, produced what Trump called "an outstanding group of decisions" — a reported cut in tariffs, a one-year pause on escalations, and renewed soybean purchases. But in the torrents of analysis flooding Chinese social media and policy circles, the subtext was unmistakable: negotiations are decided by hard power, not who yells louder.

At the heart of this recalibration lies a material reality that Washington has struggled to acknowledge: China's stranglehold on rare earth processing — controlling 80-90% of global refining capacity — has transformed from industrial advantage into geopolitical veto power. And the Busan summit represents the first time a U.S. administration has explicitly traded tariff relief for breathing room on that chokepoint.

The Magnet That Moved Mountains

The mechanics are stark. China's October 9 rare earth export controls, targeting specialized magnets essential for electric vehicles, wind turbines, and missile guidance systems, weren't mere retaliation for U.S. semiconductor bans. They were a ultimatum: the American defense-industrial base, green energy transition, and consumer electronics supply chain all converge on materials China can restrict with the stroke of a regulatory pen.

According to the reported terms circulating in Chinese policy circles — not yet formalized in joint text but repeated across multiple sourcing channels — the U.S. agreed to slash its so-called "fentanyl tariff" from 20% to 10%, reducing average levies on Chinese goods to 45-47%. In exchange, China would delay new rare earth restrictions by approximately one year while resuming purchases of American soybeans.

"If the U.S. could have crushed China, it wouldn't be haggling tariffs," wrote one widely-shared commentator, encapsulating the prevailing Chinese interpretation. The U.S. Geological Survey's own assessments suggest American rare earth refining capacity faces a 10-15 year runway to scale, even with emergency investment — a timeline that eclipses electoral cycles and renders short-term posturing moot.

The one-year "pause basket" reportedly extends beyond rare earths to include suspensions on new U.S. tariffs, certain export control escalations (including the controversial 50% ownership "look-through" rule targeting Chinese firms with partial American stakes), and a Section 301 investigation into China's maritime and shipbuilding dominance. China would reciprocally freeze corresponding countermeasures.

The G2 Semantic Shift

Perhaps more significant than the technical terms was Trump's public framing of the encounter as a "G2" meeting — a designation the White House then reposted, breaking with decades of carefully calibrated multilateralism. Chinese analysts seized on this nomenclature as implicit U.S. recognition that "the world's core is U.S.-China," a rhetorical upgrade from competitive rhetoric to grudging co-management.

"The world is big enough for two great powers — at least Trump now gets that," observed multiple commentators, reflecting a domestic narrative that positions the meeting not as Chinese concession but American acknowledgment of parity.

The venue itself carried symbolism. South Korea, caught between security dependence on Washington and economic interdependence with Beijing, served as literal middle ground. And the timing — a hastily arranged sidebar before the formal APEC proceedings — suggested urgency that Chinese observers interpreted as Trump's domestic political calendar driving engagement: midterm elections in 2026 demand farm-state victories and inflation relief, not prolonged trade wars.

The Soybean-Tariff Swap Logic

The agricultural component illuminates the bargaining architecture. U.S. soybean exports to China, suspended since mid-2024 amid escalating tariffs, represent $10 billion in annual trade and have idled 20% of American farmland capacity. Market chatter in Chinese commodity circles suggested Beijing employed explicit conditionality: full restoration of soybean purchases requires full removal of the fentanyl tariff; partial cuts yield partial orders — "we buy half if you cut half."

This isn't magnanimity but cold calculation. China's food security imperatives, heightened by 2023 droughts, demand stable imports. But Brazil and Argentina have captured 15% of China's soy market previously held by the U.S., per USDA data, creating competitive pressure that benefits Chinese buyers while punishing American farmers in politically critical states.

The rare earth leverage makes this arithmetic work. Without the pause on Chinese restrictions, U.S. electric vehicle production — including Tesla's Shanghai-dependent operations — faces material shortages within quarters. The threat concentrates minds in ways agricultural surplus cannot.

What Wasn't Discussed

Multiple Chinese sources emphasized that Taiwan was not addressed in the meeting — a notable omission given its centrality to U.S.-China tensions. Analysts interpreted this as mutual avoidance rather than resolution: Washington's $2 billion F-16 sale to Taipei in October and Beijing's ongoing gray-zone military exercises around the strait remain unaffected.

Similarly, reports that semiconductor discussions were limited or that Trump explicitly denied discussing NVIDIA's advanced Blackwell chips suggest the meeting achieved tactical de-escalation without strategic breakthrough. One commentator noted that if genuine tech export-control concessions were in play, "they would've talked longer" — the 105-minute duration signaling meaningful but bounded progress.

The 12-Month Countdown Clock

The provisional nature of these arrangements cannot be overstated. The reported one-year timeframe aligns suspiciously with both Trump's midterm pressures and Xi Jinping's 2026-2030 Five-Year Plan launch, which prioritizes "8467" sectors: eight traditional industries to stabilize, four emerging sectors including new energy, six future technologies like quantum computing, and seven foundational infrastructures.

Chinese commentators framed the pause as "breathing room" for industrial repositioning, not permanent accommodation. "Tactical easing is possible; strategic reconciliation is very hard," wrote one analyst, capturing the consensus that this represents managed competition rather than genuine rapprochement.

The enforcement mechanisms remain opaque absent formal text. And the structural asymmetries persist: China continues building global rare earth processing dominance while the U.S. subsidizes domestic chip manufacturing through the CHIPS Act, setting up continued bifurcation rather than convergence.

Supply Chain Whiplash

An underappreciated consequence flows through global logistics. If Chinese tariffs genuinely drop to the 45% range, the economic advantage of routing exports through Southeast Asian "re-export" platforms — which accounted for roughly 40% of China-U.S. trade flows — compresses dramatically. Direct shipments from Chinese coastal exporters become competitive again after factoring freight costs and margins.

This would represent a partial unwind of three years of "China+1" diversification strategies, potentially destabilizing Vietnamese and Malaysian export zones that absorbed billions in diverted foreign investment. For multinational corporations that spent heavily on supply chain redundancy, the message is unsettling: geopolitical risk doesn't trend — it whipsaws.

Hard Power, Not Volume

Perhaps the sharpest Chinese commentary cut to the philosophical core: "Talk if you will, fight if you must; we're prepared for both." This wasn't bravado but recognition that neither side can afford comprehensive rupture, yet neither trusts the other's long-term intentions.

The Busan meeting didn't resolve the U.S.-China rivalry. It priced it. And in that price discovery, rare earth refining capacity — unglamorous, capital-intensive, environmentally challenging — emerged as more valuable than tariff threats or rhetorical escalations.

As one Chinese observer noted with dark humor about the mere fact the meeting occurred: "They didn't cancel. In 2025, that's the biggest positive."

The clock on this provisional peace now ticks toward October 2026. What both sides build — or fail to build — in that window will determine whether Busan was an inflection point or merely an intermission.
