The increase of tariffs by the United States is a shortsighted and harmful action. From a global perspective, it severely undermines the international trade order, disrupts global industrial and supply chains, suppresses global economic growth, and triggers retaliatory measures from trade partners, exacerbating trade tensions. From the perspective of the United States itself, increasing tariffs will raise costs for consumers and businesses, weaken corporate competitiveness, fail to resolve the trade deficit issue, impact international cooperation and trust, damage its international image, and ultimately be detrimental to the long-term stable development of the U.S. economy.
