US Tightens Chip Export Controls on China

The Trump administration has imposed new export controls requiring U.S. and some foreign companies to obtain licenses before selling critical electronic design automation (EDA) software and semiconductor-related products to China, including sales to subsidiaries. Major providers such as Synopsys, Cadence, and Siemens EDA have suspended services and new orders for Chinese clients in response. The restrictions also cover chemicals, machine tools, and aviation parts, causing companies to withdraw financial forecasts amid uncertainty. U.S. officials state the measures aim to prevent military use and protect technological leadership, while the Chinese embassy calls the rules discriminatory and urges reversal. The moves have intensified U.S.-China trade tensions and prompted Beijing to accelerate efforts for technological self-reliance. The new controls are expected to impact U.S. business revenues in China and hinder China's advanced chip development, affecting the global tech industry.
