The US China trade war began in 2018 when the Trump administration imposed tariffs on Chinese goods, escalating dramatically throughout 2019 with successive rounds of tariff increases.
By mid 2019, the conflict had become the defining economic confrontation of the era, with both nations implementing retaliatory measures that disrupted global supply chains.
The 2019 phase saw tariffs expand across multiple product categories, reaching over 370 billion dollars in affected Chinese imports. Recent analysis reveals that diverging US China trade data point to tariff evasion, suggesting companies redirected shipments through third countries to circumvent duties.
The trade war affected major trading partners including Canada, which faced separate tariff disputes. The conflict shaped global trade policy through 2026, with tariff and trade issues remaining among the most heavily tracked geopolitical signals, accounting for 54 tracked events in comprehensive monitoring systems.
