Taiwan has added China’s tech titan Huawei and chip giant Semiconductor Manufacturing International Corporation (SMIC) to its export control list, stepping up efforts to align with Washington’s crackdown on companies driving Beijing’s artificial intelligence ambitions.

Chinese companies Huawei and SMIC may have a difficult time accessing resources needed to build AI chips, due to Taiwanese export controls.

Two of the most important companies behind China’s semiconductor self-sufficiency and AI supremacy hopes were dealt a blow on Saturday, with their addition to Taiwan’s strategic high-tech commodities entity list.
