The USA-China tensions reflect a complex rivalry rooted in ideology, trade, technology, and global influence. Once economic partners, they now compete fiercely across multiple domains. Trade wars, tech bans, and intellectual property disputes have intensified mistrust. The U.S. seeks to contain China's rise, while China challenges U.S. dominance. Taiwan remains the most volatile flashpoint, with military escalations risking open conflict. Cybersecurity, AI, and semiconductors are modern battlegrounds. Both nations court allies, reshape alliances, and weaponize supply chains. This struggle isn’t just bilateral—it defines the 21st century’s geopolitical order. Cooperation is possible, but competition is the current defining force of their relationship.
