Mercedes-Benz has joined its Chinese joint venture partner Geely's legal challenge at the Court of Justice of the European Union (CJEU) against EU tariffs on China-made electric vehicles, a company spokesperson said on Tuesday.

Mercedes-Benz Group AG is joining a Geely lawsuit against European Union tariffs on electric cars imported from China, adding to a flurry of legal cases targeting the duties.

BMW said in a statement that EU duties on battery electric vehicles “harm business models of globally active companies.”

Tesla and Germany’s BMW are suing the European Commission, joining a growing band of Chinese automakers to oppose the European Union on its punitive tariffs on electric vehicles.
