President-elect Donald Trump announced sweeping tariffs on goods from Mexico, Canada, and China to address border security and drug smuggling, proposing 25% tariffs on Mexico and Canada and an additional 10% on China. Mexican President Claudia Sheinbaum criticized the move, warning of inflation, job losses, and potential counter-tariffs, while also blaming U.S. public health and spending priorities for the migration and drug crises. China's response emphasized that tariffs harm all parties. Economists predict severe impacts on industries like light manufacturing and steel, while markets, such as the Mexican peso, already show volatility in response to Trump’s bold trade measures.
