US AI chip export controls (2022)
The U.S. Commerce Department restricted exports of advanced AI chips and chipmaking equipment to China. Nvidia's most advanced processors could no longer be sold there without a license.
Nvidia designed slower chips for the Chinese market, and the controls were expanded in 2023 and 2024.
The rules pushed China to build domestic chip capacity and to look for ways to train models abroad.
China's draft is a mirror move at the model layer, after the U.S. restricted the hardware layer.
