US and China open Cold War-style AI hotline

The White House announced Friday that the US and China now have an AI hotline. The announcement followed Chinese President Xi Jinping's state visit to Washington. A new US-China Super Intelligence Dialogue will study the risks and benefits of AI. The first talks are due by November. A separate channel will handle AI incidents. US Trade Representative Jamieson Greer compared the channel with the red phone between the Kremlin and the White House during the Cold War. Xi said AI should develop "always under human control," according to CBS. Hours before the talks, Trump posted that superintelligence would be a major discussion topic. Trump also posted that China held the same position. Trump said the US Department of Justice was the US guardrail. Treasury Secretary Scott Bessent had opened AI risk talks with China by September 16. Bessent insisted that the US would not slow its own AI work. Stanford's 2026 AI Index found that private investors put $285.9 billion into American AI in 2025. Private investors put $12.4 billion into Chinese AI in 2025. Stanford's report said government funding would likely push China's actual total higher. As of March, the best US model led its top Chinese rival by 2.7%. Draft guidance for UK government teams tells staff to use AI only when needed. The guidance aims to reduce AI's environmental impact. Staff should first ask whether a spreadsheet or search engine can do the task. If staff need AI, the guidance says they should choose the smallest model that works. It gives Gemini Flash instead of Gemini Pro as an example. The guidance says prompts should be short and few. It says staff do not need to say "thankyou." Staff must check AI answers for accuracy. Staff must disclose when AI helped create or edit content. Trump and Xi will meet again in November at the Asia-Pacific Economic Cooperation summit in Shenzhen. The first AI talks are due by then.
