U.S. Secretary of State Marco Rubio is wrapping his up his second and final day at a Southeast Asian security conference with a high-stakes meeting with his Chinese counterpart as tensions grow between Washington and Beijing over issues from trade to security and China's support for Russia's war in Ukraine.

The meeting takes place on the sidelines of a Southeast Asian summit, where Washington and Beijing are each attempting to exert their influence.

Beijing has launched a fiery response to the U.S. President Donald Trump’s announcement of a sweeping 50% tariff on Chinese copper imports, calling the move reckless and “dangerous.” Chinese officials accused Trump of reigniting an aggressive trade war that threatens global markets and bilateral stability.

U.S. President Donald Trump launched his global tariff assault into overdrive on Wednesday, announcing a new 50% tariff on U.S. copper imports and a 50% duty on goods from Brazil, both to start on August 1.
