US and China Agree to AI Hotline and Tariff Cuts After Summit

After a summit between President Trump and President Xi in late September 2026, the United States and China agreed to set up a direct communication channel for artificial intelligence incidents. The two countries also agreed to tariff reductions worth about 30 billion dollars.

The AI hotline is meant to give both sides a way to communicate if an AI-related incident occurs. The tariff cuts are part of the same set of agreements reached at the summit.
