Treasury Secretary Janet Yellen is set to criticize former President Donald Trump's proposed tariffs, describing them as 'deeply misguided' and potentially harmful to both American consumers and businesses. In her speech at the Council on Foreign Relations, Yellen will argue that Trump's plan for sweeping, untargeted tariffs could lead to increased prices and reduced competitiveness for American firms. Her remarks caution against a unilateral approach to economic policy, emphasizing the importance of multilateral cooperation in addressing global issues such as supply chain disruptions and climate change. Yellen supports the Biden administration's strategic investments in U.S. manufacturing and calls for maintaining a balanced economic relationship with China, despite their trade practices. Trump's tariff proposals, which include levies of up to 60% on Chinese imports, have been a central theme of his campaign despite economists warning they could exacerbate inflation. Yellen's comments highlight a broader debate on trade policy as the election approaches.
