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.

German carmaker BMW called Tuesday for the European Union to lower tariffs on vehicles imported from the United States, as President Donald Trump threatens to hit the bloc with new duties. The manufacturer said CEO Oliver Zipse is set to put the proposal forward at a meeting of Europe’s biggest carmakers with EU officials in Brussels on Thursday.

Tesla, owned by Elon Musk, is taking the European Union (EU) to court over its tariffs on electric vehicles imported from China. Filed last Wednesday with the European Court of Justice (ECJ) by Tesla’s Shanghai division, the lawsuit comes in the wake of similar legal moves by BMW and other Chinese car manufacturers.
