Overview

• The White House announced a 100% additional tariff on Chinese goods, with President Trump saying the measure will take effect in November in response to tougher Chinese export restrictions.
• Beijing escalated countermeasures with an antitrust investigation into Qualcomm and new fees for U.S. ships calling at Chinese ports.
• China’s latest rules tighten oversight of rare‑earth technologies and require permits for products using Chinese materials, heightening risks for U.S. manufacturers reliant on these inputs.
• U.S. Trade Representative Katherine Tai’s successor, Marisa C. Glazer, said Washington will evaluate next steps in the coming days and act decisively if talks stall, and Trump suggested the face‑to‑face with Xi could be canceled.
• Earlier tariff surges this year were pared back after market turmoil, but experts caution that renewed retaliation could again destabilize the global economy.
