Tech war: China’s top chip equipment maker removes US employees from product development after Washington imposes restrictions

China’s top semiconductor equipment maker Naura Technology Group has told its American employees in China to stop taking part in component and machinery development to comply with Washington’s restrictions on the involvement of US citizens in key facilities on the mainland, according to a source briefed on the decision.

In an internal notice, the Beijing-based company asked its American engineers to stop working on research and development projects with immediate effect, the source said.
