China on Wednesday said it would launch a formal probe looking into EU practices during an anti-subsidy investigation into Chinese firms.

"The Ministry of Commerce will conduct a trade and investment barrier investigation into the relevant practices adopted by the EU in its investigation of Chinese enterprises," the ministry said in a note on its website.

Ministry officials said they had decided to launch the probe following a complaint made by the national chamber of commerce for importing and exporting machinery and electronics.

The complaint mainly dealt with "products such as railway locomotives, photovoltaics, wind power and security inspection equipment", according to the ministry.

The investigation will last from July 10 to January 10, 2025, and could be extended to April 10, 2025 under special conditions, the ministry said. (Agencies)
