Foreign Companies Face Retaliation in China Amid US-Led Tech Blockade.

China has started a "surgical" retaliation against foreign companies after the US-led tech blockade, which has resulted in Chinese companies being cut off from key technologies. The retaliation includes targeting foreign companies that have cut off supplies to Chinese firms, as well as imposing restrictions on foreign firms operating in China. This marks a significant escalation in the ongoing trade tensions between China and the US.
