China Expands AI Brain Drain Controls Beyond DeepSeek

China is weaponizing passport restrictions to prevent its top AI researchers from leaving, extending controls that started at DeepSeek to other private firms. The move reflects state-level anxiety about talent flight in a competitive global AI race. Frontier AI researchers are now treated as strategic assets equivalent to military scientists, raising the cost of working in China's private sector and potentially accelerating brain drain as researchers seek exits before restrictions tighten further.
