The European Union's AI Act classifies AI systems by risk level and bans certain uses entirely, including real-time biometric surveillance in public spaces and social scoring systems. China requires AI-generated content to be labeled and mandates that algorithms align with "core socialist values." The United States has taken a more sector-specific approach, issuing executive orders and relying on existing agencies to regulate AI within their domains. Meanwhile, countries like Singapore and the UAE are positioning themselves as AI-friendly jurisdictions to attract investment. The regulatory landscape is fragmented, evolving rapidly, and high-stakes. Companies building AI for global markets must navigate a patchwork of requirements that sometimes conflict. Too little regulation risks harm; too much risks pushing innovation underground or offshore. Getting this balance right may be one of the defining policy challenges of the decade.
