Tech, Semiconductor Stocks Slammed as China Tightens Controls

The developments reignited U.S.-China trade tensions, weighing heavily on semiconductor and AI-linked shares. Analysts said Beijing’s move to tighten mineral exports adds supply-chain uncertainty, exacerbating investor caution in a sector already pressured by global demand slowdown and geopolitical friction.
