Trump's tariff policy toward China was a radical implementation of his "America First" agenda. – Starting in 2017, he imposed a series of high tariffs on Chinese imports, aiming to reduce the trade deficit, boost domestic manufacturing, and create jobs. – These moves also catered to certain domestic interest groups and electoral politics. – In his second term, he signed an executive order in February 2025 imposing a 10% tariff on Chinese goods, followed by a "reciprocal tariff" order in April, raising the rate to 34%. – These policies severely impacted China’s exports to the U.S., causing order losses and supply chain disruptions. – In response, China took countermeasures and expanded into diverse markets. – The international community strongly opposed the U.S. actions, which undermined the global multilateral trade system. – Trump's tariff strategy significantly reshaped U.S.-China trade relations and added lasting uncertainty to the global economy, making it a key issue of global concern.
