7 China approves ByteDance and Tencent to import 10,000 H200 chips each¶

China approved ByteDance and Tencent to each import 10,000 NVIDIA H200 AI chips, with other companies expected to follow. The move reflects China's shortage of advanced chipmaking equipment as the U.S. restricts exports of EUV and DUV lithography machines, limiting domestic AI development capacity.

ByteDance and Tencent each approved for 10,000 H200 chips
H200 is most powerful U.S. chip cleared for China export, 2+ generations behind Nvidia's advanced chips
U.S. authorized Chinese firms to purchase up to 100,000 H200 chips each
Most H200s required to stay outside mainland China; directed to Hong Kong data centers
Nvidia holds ~500,000 H200 chips in reserve for Chinese customers
