The Trump administration plans to slow the shipment of commercial jet parts to China amid escalating resource nationalism. This move aims to prevent China from stockpiling critical aviation components. The Commerce Department has slowed export licensing for these parts and is considering new regulations. These new rules could make it easier to restrict exports of landing gear and other aircraft components. Additionally, a new licensing requirement for aviation hydraulic fluid is being explored. These actions are in response to China's increased willingness to restrict critical material exports to the US. This has already led to shortages of materials like gallium and germanium. The US strategy appears to be retaliating by targeting China's supply chains. These actions follow a lack of resolution on rare earth issues between the US and China. The US is seeking to create a more level playing field in trade relations.
