After Japanese Prime Minister Sanae Takaichi's remarks about "intervening in Taiwan in an emergency," China, which began export controls against Japan, said it would launch an anti-dumping investigation into semiconductor process chemicals imported from Japan.
China's Ministry of Commerce said in a notice on its website on the 7th that it would begin an anti-dumping investigation starting that day into dichlorosilane, a semiconductor process chemical imported from Japan. Dichlorosilane is a key chemical used for nitride film deposition in semiconductor chip manufacturing. Earlier, the ministry received an application from domestic corporations for a related anti-dumping investigation on Dec. 8, 2025.
The ministry said, "After reviewing those surveyed products, similar products in China, the impact of those surveyed products on Chinese industry, and the countries concerned, we determined that the conditions for initiating an investigation were met."
