US and Allies Restrict Advanced Chip Exports to China, Raising Tensions

Japan has imposed export controls on chipmaking tools to align with US policy restricting China's access to advanced semiconductor technology.
China has appealed to Japan not to disrupt the semiconductor industry or bilateral cooperation, but Japan is coordinating controls with the US and Netherlands.
The controls worry some Japanese officials who believe the US approach may hamper coordination and provoke Beijing unnecessarily.
China relies on Western and Japanese technology for advanced chips and has invested heavily in building domestic chip foundries.
The Chinese government has responded slowly, possibly to avoid disrupting emerging tech industries reliant on foreign equipment.
