China Commerce Ministry warns EU against discriminatory trade measures

The signal here is procedural rather than substantive: Beijing is flagging WTO exposure before any EU measure exists, which suggests the hybrid-vehicle understanding is being treated as a template that could travel to chemicals and beyond. That matters most for European downstream manufacturers, who would absorb higher input costs, and for the credibility of the WTO-rules framing both sides invoke. Whether the EU's study actually moves from review to proposed restrictions is the open question.
