The US-China tariff war reshapes the global manufacturing landscape, structural adjustment of electronic control demand and corporate strategic breakthrough

Since the United States upgraded its tariff policy on China in 2024, the global manufacturing supply chain has been undergoing a deep adjustment. Labor-intensive industries represented by power tools, auto parts, and consumer electronics have accelerated their migration to low-cost regions such as Southeast Asia, Mexico, and Eastern Europe. It is worth noting that the "reciprocal tariff" policy implemented by the United States in April 2025 further changed the migration logic: Southeast Asian countries such as Vietnam and Thailand face high tariffs of 46% and 36%, forcing companies to shift their production capacity to regions with lower tax rates such as Africa and Latin America.
