US sharply escalates tariffs on Chinese goods, raising rates significantly (e.g., from 34% to 84%) and imposing high duties (up to 90%) on low-value imports, in direct response to China's tariff retaliation against previous US actions. The US is doubling down on its protectionist trade war with China. By drastically increasing tariffs and duties on low-value imports after Beijing retaliated, the administration prioritizes confrontational escalation over trade stability. This action is likely to increase costs for American consumers and businesses, further disrupt supply chains, and risks worsening economic friction without guaranteed success in resolving complex trade imbalances or achieving stated security goals.
