NEW: Biden administration plans stricter export controls on advanced AI chips to maintain U.S. leadership and block adversaries like China and Russia from accessing critical technologies. The new rules divide countries into three tiers: 1. Tier 1: U.S. and 18 allies, including Germany and Japan, with full access. 2. Tier 2: Most countries face limits of 50,000 GPUs but can exceed them under a “validated end user” (VEU) designation by meeting U.S. standards. 3. Tier 3: Adversaries like China face near-total bans. Türkiye likely falls under Tier 2, with its AI chip access dependent on compliance with U.S. rules. Chipmakers, including Nvidia, criticized the policy, warning it could harm economic growth and bypass proper industry consultation. Source: Bloomberg
