The U.S.A–China Trade War and Its Global Impact: Assessing Its Effects on Global Trade and Economic Stability

Abstract

The U.S.A–China trade war represents one of the most significant episodes of trade-policy conflict in the contemporary international economic system, with consequences extending beyond bilateral trade relations to global trade flows, economic stability, investment patterns, and international supply chains. This study examined the global impact of the U.S.A–China trade war, with particular emphasis on changes in global trade integration, economic uncertainty, foreign direct investment, trade diversion, and supply-chain restructuring. A qualitative research design was employed using a systematic documentary review of peer-reviewed research articles, academic publications, reports from international organizations, newspapers, magazines, and other credible published sources. Purposive sampling was used to identify sources directly relevant to the research objectives, while thematic analysis and comparative analysis were applied to identify recurring patterns and differences across the evidence. The findings demonstrated that tariff escalation substantially altered bilateral trade relations and contributed to the diversion and reallocation of trade toward alternative economies, particularly Mexico, Vietnam, Taiwan, India, and other Southeast Asian countries. The analysis further indicated that the decline in direct U.S.A–China trade did not represent complete economic decoupling, as Chinese inputs and value-added remained embedded within several international production and supply-chain networks. The trade war also contributed to increased trade-policy uncertainty, encouraging firms and governments to reconsider sourcing, investment, and production strategies. Evidence concerning foreign direct investment indicated substantial fluctuations during the study period, while recent developments demonstrated increasing investment toward alternative production locations and greater emphasis on supply-chain diversification. The findings further suggested that the conflict contributed to the regionalization and strategic reorganization of global value chains, with economic security, resilience, and geopolitical considerations becoming increasingly important alongside traditional cost-efficiency considerations. However, the study recognizes that changes in global economic growth, trade, and investment cannot be attributed exclusively to the trade war because other major shocks, particularly the COVID-19 pandemic, geopolitical tensions, and changing macroeconomic conditions, also influenced global economic outcomes. Overall, the study concludes that the U.S.A–China trade war transformed from a bilateral tariff dispute into a broader structural force influencing the organization and predictability of the international economic system. Rather than producing complete deglobalization, the conflict appears to have encouraged a reconfiguration of globalization characterized by diversification, regionalization, strategic sourcing, and increased attention to geopolitical risk. The study highlights the importance of maintaining predictable international trade rules and strengthening multilateral cooperation to limit excessive economic fragmentation and support global economic stability.
