China has filed a complaint with the World Trade Organization (WTO) against the European Union (EU) over tariffs of up to 37.6% on Chinese-made electric vehicles (EVs), which the EU claims benefit unfairly from Chines government subsidies. China argues that its support for the EV industry complies with WTO rules and that the tariffs undermine global cooperation on climate change. The two parties have until early November to resolve the issue before the tariffs become official. Meanwhile, China's auto exports have increased, while domestic sales have declined. In retaliation, China is investigating French cognac and European pork exports, raising concerns about a potential trade war.
