China issues questionnaires on US chip anti-dumping probe

China's commerce ministry has issued questionnaires to companies in its anti-dumping case into US analog chips, it said in a statement on Wednesday.

Foreign exporters and manufacturers and domestic importers and manufacturers of the chips were asked to complete the forms.

Last month China initiated an investigation looking into the suspected dumping of imports of some US analog chips used in devices such as hearing aids, Wi-Fi routers and temperature sensors.
