In a new escalation of international trade tensions, China has officially filed a complaint against the European Union with the World Trade Organization (WTO). This action follows the EU's decision to impose significant tariffs, ranging from 8% to 35%, on electric vehicles imported from China. According to the European Union, these taxes aim to correct what is deemed unfair competition due to Chinese state subsidies. In response to this measure, China retaliates and denounces an infringement on free trade principles. This conflict arises as both economic powers attempt to position themselves as global leaders in ecological transition and technological innovation.
