The United States is slowing exports of aircraft parts to China, according to people familiar with the matter, as the Trump administration considers using the aviation supply chain as leverage in ongoing trade negotiations with Beijing.

The U.S. Commerce Department has slowed some export licenses for aircraft parts bound for China in recent weeks, Reuters reported. Officials have also considered additional restrictions covering products such as landing gear and aviation hydraulic fluid.

The measures could affect China's state-owned COMAC, which is developing its commercial aircraft business. U.S. aerospace suppliers provide components used by Chinese airlines and aircraft manufacturers, making the supply relationship important for both sides.

China has also sought several years of spare-parts supplies for 200 Boeing aircraft purchased by Chinese carriers. The status of that request remains unclear, according to Reuters.

The developments come as Washington and Beijing continue negotiations involving rare earth minerals, agricultural trade, artificial intelligence and other economic issues. The two countries recently extended their trade truce, giving negotiators additional time to address outstanding disputes.

The aviation sector now faces increased attention as aircraft components become part of the broader U.S.-China trade and supply-chain negotiations.
