The United States recently announced an increase in tariffs on China, involving key areas such as electric vehicles, lithium batteries, photovoltaic products, and semiconductors. The tariff on electric vehicles has been significantly raised from 25% to 100%. This move aims to protect domestic industries but may push up inflation in the United States and exacerbate trade frictions. China has expressed strong opposition and called for adherence to WTO rules. The global supply chain may be impacted, and companies face rising cost pressures. Analysts believe that the tariff war may delay the green transition, affect China-U.S. economic and trade relations, and even trigger a new round of global trade tensions.
