  • U.S. imposes bans on jet engine tech, semiconductor software and advanced materials to China.
  • Visa revocations target Chinese students in sensitive research fields.
  • China’s rare earth export restrictions spurn U.S. retaliation and raise supply chain security concerns.
  • Pentagon halts fighter jet production due to Chinese alloy discovery in components.
  • 90-day trade truce risks collapse as both nations escalate economic brinkmanship.
The Trump administration has unleashed sweeping sanctions on China, halting exports of critical aerospace and semiconductor technologies while revoking visas for Chinese students in strategic fields — a direct retaliation against Beijing’s rare earth mineral restrictions. This escalation comes after Pentagon officials discovered a Chinese alloy in U.S. fighter jets, underscoring supply chain vulnerabilities. With both nations under a precarious 90-day tariff truce, the moves signal a deepening industrial cold war threatening global trade and national security.

“Decisive action” against untrustworthy partners

Secretary of State Marco Rubio announced Wednesday that visas for Chinese individuals enrolled in fields such as robotics, artificial intelligence, or aerospace would be aggressively revoked, targeting suspected CCP ties. “We cannot allow these resources or education opportunities to flow to China’s strategic warfare initiatives,” Rubio stated in an X post. The U.S. Commerce Department simultaneously suspended exports of jet engine parts to China’s state-owned Commercial Aircraft Corp (COMAC), crippling its C919 passenger jet program. The aircraft, designed to rival Boeing and Airbus, relies on engines from GE Aerospace-Safran — a U.S.-French joint venture. Analysts warn China’s aviation sector faces a prolonged setback, as domestic engine production remains decades behind. “We’re seeing a calculated escalation to pressure China where it hurts,” said Paul Triolo of the Eurasia Group. “The Pentagon’s recent discovery of Chinese alloy in U.S. military jets highlights why oversight of supply chains is non-negotiable.”

Tech and rare earths: The new economic battlefield

The U.S. also suspended semiconductor design software exports from firms like Synopsys and Cadence — tools essential for China’s efforts to build advanced chips. China’s push for chip self-reliance, spurred by U.S.-led export curbs, stalled as Washington blocked vital design tools. China had retaliated against earlier U.S. tariffs by restricting exports of rare earth metals and magnets — critical for tech, defense and green energy sectors. White House officials accused Beijing of weaponizing these materials to coerce economic concessions. “This isn’t tit-for-tat — it’s a strategic effort to secure control over 21st-century technologies,” said a Commerce Department spokesperson.

The shift from trade partners to strategic rivals

The U.S. and China were once intertwined economically, but both now treat each other as untrustworthy partners. In 2010, China briefly cut rare earth exports to Japan during a territorial dispute, signaling its willingness to weaponize resources. Today, China’s dominance in rare earth refining and recycling — 90% of global supply — has given it unmatched leverage. The U.S., meanwhile, relies on China for 80% of rare earth magnets, used in everything from missiles to electric vehicles. The Pentagon’s recent suspension of the F-35 production — a $400 billion program — after finding a Chinese-made alloy in parts highlights the existential risks of reliance. “The Pentagon incident was a wake-up call,” said Rep. Mike Gallagher (R-WI), a National Security Committee member. “If foreign adversaries can undermine our military supply chains, then we must prioritize domestic production and accountability.”

Broader implications: Trade, security and the future of global industry

The export bans underscore a broader Republican agenda prioritizing national security over free trade doctrines. Supporters argue domestic manufacturing and strict oversight of imports are vital to preserving liberties and preventing future vulnerabilities. Critics, however, warn of depressed global growth and retaliatory tariffs damaging U.S. businesses. “This risks decoupling our economy from China’s without solving deeper security issues,” said economist Matthew Slaughter. President Trump’s actions align with his ’America First’ stance, framing China’s economic ambitions as a clear threat. “We’re no longer giving Beijing a free pass to hollow out our industries,” a senior administration official said.

A precarious truce and the path forward

With the 90-day tariff truce set to expire in mid-August, negotiations face steep odds. China’s token resumption of rare earth exports has done little to calm U.S. concerns. Meanwhile, U.S. moves on visas and supply chains send a stark message: Beijing cannot continue undermining global supply chains without consequences. As the Pentagon recalibrates its sourcing strategies to avoid foreign contamination, the administration insists this is defensive rather than destructive. “The goal is to build resilience — not to disrupt the world economy,” the Commerce spokesperson added. The next 100 days will test whether this aggressive posture is a temporary shield or the blueprint for permanent economic detachment. One thing is clear: the future of trade — and perhaps national security — will be forged in the clash over supply chain control.
