Is Hitachi SEM prohibited from being sold in China?

There is no ban on sales. As far as I know, Hitachi High-tech Company was fined by the US government for exporting dual-use products to China, but it was not banned from exporting products such as scanning electron microscope to China. At present, Hitachi High-tech Company sells products such as scanning electron microscope in China market. However, due to the changes in international trade laws and regulations and the company's business strategy, the specific situation may change at any time.
