China has launched an antitrust investigation into Qualcomm, a major American semiconductor company, just hours before President Donald Trump announced a new one hundred percent tariff on Chinese imports. The probe centers on Qualcomm's recent acquisition of Israeli chip designer Autotalks and whether the company violated Chinese antitrust laws. This move is part of a broader escalation in tensions between China and the United States, with both sides imposing new trade restrictions and targeting each other's technology sectors. The dispute threatens to further disrupt global chip supply chains and complicates upcoming diplomatic engagements between the two countries.
