U.S.-China "red telephone" could bring a Cold War guardrail to AI

As the Trump-Xi summit unfolds in Washington, the U.S. and China are considering an emergency red phone for AI emergencies. This development is significant because U.S.-China relations are so tense that an AI hotline could become the summit's most meaningful outcome. President Trump has been aggressive in his stance against AI doomsayers, stating that the U.S. would not hinder AI development to maintain its lead over China.

However, leading AI labs largely agree on the urgency to address China, but disagree with Trump's conclusion that the race is the main concern.

China, under President Xi Jinping, is equally determined to win the AI race. Xi is wary of falling behind and has pushed for open-source models worldwide while portraying U.S. chip controls as efforts to hold China back. Beijing is more concerned about near-term dangers like cyberattacks, malicious use, and disruptions to critical infrastructure rather than long-term extinction scenarios.

The proposal for an AI hotline draws a parallel to the Cold War-era hotline between Washington and Moscow, which was established after the Cuban Missile Crisis to prevent accidents and ambiguity from escalating into nuclear Armageddon. However, defining what would trigger the red phone remains unclear. In an AI catastrophe, such as a frontier model causing a major cyberattack on critical infrastructure, the alarm may initially sound within a private company rather than a government command center.

The challenge lies in sharing sensitive information between the lab and officials before fully understanding the threat. Washington and Beijing already have crisis hotlines, but their effectiveness has been questioned in the past. For instance, China suspended military contacts after Nancy Pelosi's 2022 Taiwan visit, and declined a Pentagon request for a call after the U.S. shot down its surveillance balloon.

During the COVID-19 pandemic, a transparent and cooperative approach was overshadowed by a bitter blame game between the U.S. and China. The proposal for an AI hotline underscores that AI is now a critical arena of U.S.-China competition, and any serious failure could quickly turn into a shared crisis.
