The US-China trade war officially began on July 6, 2018, when the United States imposed 25 percent tariffs on 34 billion USD worth of Chinese goods. This action marked a significant escalation of economic tensions between the two global powers, triggering immediate retaliatory measures from Beijing.

The trade war stemmed from longstanding grievances regarding China's trade practices, including intellectual property theft, forced technology transfers, state subsidies, and a persistent trade imbalance. The US administration argued these practices created an unfair playing field for American businesses. Following the initial July 2018 tariffs, both nations steadily escalated duties, broadening the scope to include hundreds of billions of dollars worth of goods. This tit-for-tat imposition of tariffs impacted various sectors, from agriculture and manufacturing to technology.

The conflict represented a shift from traditional diplomatic and economic engagement to a more confrontational approach, signaling a new era in US-China relations. The geopolitical landscape was increasingly defined by this economic rivalry, reflecting broader competition in areas such as technological dominance and strategic influence.
