U.S. President Donald Trump has escalated trade tensions by imposing a 100% tariff on all Chinese imports effective November 1, 2025.

Analysts warn the move could invite retaliation from Beijing, disrupt global trade flows, and heighten geopolitical and economic instability ahead of key policy discussions.
