Germany has joined calls for expanded safeguards on artificial intelligence development, as a broader international debate over the technology's risks accelerates. The push comes amid warnings from researchers — including one who has worked at both Anthropic and OpenAI, the two leading U.S. AI developers — that unchecked AI poses existential dangers, and as governments worldwide grapple with how to regulate a rapidly evolving sector. The debate is now intersecting with geopolitics, with an upcoming summit between U.S. President Donald Trump and China's Xi Jinping seen as a potential, if uncertain, opportunity to establish shared safety commitments between the world's two dominant AI powers.
