How Trump 2.0 tariffs evolved and stacked in 2025.
China's counter-strategy using critical minerals.
Impact of tech bans and reversals on semiconductors.
Prospects for decoupling and 2026 relations.

📝Summary

The US-China Trade War has reignited under Trump 2.0 with escalating tariffs up to 145% and tightened tech export controls, countered by China's rare earth export restrictions.

A fragile October 2025 truce offers temporary relief, but decoupling efforts persist amid supply chain shifts.

Tensions shape global trade in 2026, balancing economic rivalry and strategic leverage.

ℹ️Quick Facts

US tariffs on Chinese goods reached **145%** in 2025 escalations.
China imposed **25% tariffs** on US aluminum, airplanes, pork, and soybeans in retaliation.
Trump 2.0 banned Nvidia H20 chip exports to China in February 2025, later reversed due to mineral shortages.
October 30, 2025: Trump-Xi truce in Busan halted new tariffs for one year.

💡Key Takeaways

Tariffs stack cumulatively, pushing effective rates to **54%+** on Chinese imports.
China's rare earth monopoly forced US retreats from strict tech bans, shifting to 'G2' bargaining.
Supply chains reroute via Vietnam and others, with US targeting transshipments via **40% tariffs**.
No rebalancing likely; China's overproduction and US consumption gap endures.

The second Trump administration supercharged the trade war in 2025, imposing tariffs stacking to 145% on Chinese goods amid accusations of 67% barriers by China. April saw a 34% hike, confirming 54% effective rates starting one week later. Retaliation followed: China hit 128 US products with 25% on aluminum, planes, pork, soybeans, and 15% on others.

De minimis loopholes closed too—executive order from April 8 raised duties to 90% or $75 per postal item, doubling to $150 by June. USTR added 100% on Chinese cranes and maritime gear in October 2025. These moves aimed at reciprocity but sparked supply disruptions.

Tech bans ramped up: February 2025 Nvidia H20 export ban to China, plus imminent ASML restrictions threatening semiconductor nodes. US pushed to halt servicing of Chinese production tools. Investment curbs and export controls targeted Chinese entities acquiring US tech.

China weaponized critical minerals, slashing rare earth exports and crippling US defense industries. This forced Trump to reverse H20 bans and delay rules, pivoting from tech dominance to bargaining. Beijing secured narrow, technical talks over structural US demands.

G20-style relief came October 30, 2025, in Busan: Trump-Xi one-year truce maintained prior tariffs but paused new ones. An end-October trade deal cut tariffs 10 points, yet shipments fell as chains rerouted.

US eyed transshipments, striking Vietnam deal with 40% tariffs on third-country goods. NSS 2025 flagged Chinese factories in a dozen nations feeding indirect imports. Despite booming Chinese exports, decoupling advances via targeted sanctions.

Tensions simmer into 2026; sweeping hikes off-table, but targeted duties on sensitive sectors loom. Export licenses may ease for non-sensitive US firms, while defense links stay barred. China's mineral grip endures as leverage.

Trade War 2.0 won't rebalance deficits—China's production glut meets US consumption without reform. Expect elevated friction through 2035, less acute short-term, focused on industrial defense. Global firms adapt to bifurcated chains.

⚠️Things to Note

De minimis exemption tariffs on small Chinese packages hit **90% or $75/item** from May 2025.
US finalized **100% tariffs** on Chinese EVs, **50%** on solar cells in 2024, phased through 2027.
Targeted measures on cranes, steel, and maritime gear continue despite truce.
Rare earths remain China's key leverage in tech and defense disputes.
