Both Beijing and Washington have taken steps to restrict the export of goods, machinery, and technology that are deemed essential for maintaining national security. In response to arms shipments to Taiwan, a self-governing island it claims as its own, China has also placed restrictions on a few American aerospace and defence companies. According to the notification from the Commerce Ministry, the controls would also include technologies utilised in the design, manufacture, and usage of the equipment, such as simulation data, design drawings, process specifications, process parameters, and processing methods. It's unclear what the change will mean overall. China exports many aerospace and aircraft parts, including engine parts. It has created its own jet engines as well. However, for essential aeroplane parts, it continues to rely on foreign sources. It has started to produce using its own technology and manufacturers.
