Key House committee asks five American, Dutch and Japanese companies to detail their sales volume and customer base on the mainland

On Thursday, the Democratic and Republican leaders of the House select committee on China sent letters to five American, Dutch and Japanese companies, requesting detailed information about the companies’ sales volume and customer base on the mainland and highlighting national-security concerns over China’s technological development.

Information from the companies would help the committee understand the flow of chipmaking equipment to China and its role in developing the country’s chip manufacturing base, the lawmakers said.

The targeted firms include three US-based companies – Applied Materials, Lam Research and KLA – as well as Netherlands-based ASML and Japanese firm Tokyo Electron. The companies did not immediately respond to requests for comment.
