On February 21, Jin10 reported that the German business community has responded cautiously to the U.S. Supreme Court's ruling deeming the Trump administration's large-scale tariffs illegal. According to Jin10, Treier, the head of foreign trade at the German Chamber of Commerce and Industry, noted that even if the ruling takes effect, the U.S. government still possesses other tools to impose trade restrictions. Richterberg, the head of foreign economic affairs at the German Mechanical Engineering Industry Association, also warned that the direction of related policies remains uncertain, as the U.S. government has various alternative legal bases to continue implementing global tariff measures.
