Beijing has pushed back against a US decision aimed at curbing Chinese-made artificial intelligence chips, a first sign of discord between the world’s two largest economies since they agreed to a trade truce last weekend.

China on Thursday accused the United States of "abusing export control measures" and urged Washington to correct its practices after the U.S. issued guidance warning companies not to use Huawei's Ascend AI chips.

New guidance on US export rules could deter Chinese firms with global ambitions from using Huawei processors, analysts say.
