US and Chinese leaders have shown no willingness to slow frontier AI development despite establishing a bilateral Super Intelligence Dialogue and incident notification channel during the September 2026 Trump-Xi summit. President Trump has repeatedly stated the US will not apply brakes to maintain its lead in large language models and advanced semiconductors, while Beijing prioritizes rapid capability gains alongside centralized safety controls. Both sides rejected calls for deliberate pacing from industry figures, favoring voluntary US self-regulation and Chinese risk frameworks over mutual limits. The November follow-up talks could introduce narrow safety protocols, yet entrenched competition and differing governance approaches make any 2026 agreement to restrain the AI arms race highly improbable.
