BEIJING (Reuters) -The United States is exaggerating Huawei's achievements when it comes to the Ascend AI chip, the chief executive of China's Huawei Technologies said, according to Chinese state media.

Huawei's founder Ren Zhengfei said the company uses group computing to supplement single chips, according to an article by the People's Daily on Tuesday.

The U.S. Commerce Department last month published guidance warning that companies risked violating U.S. export controls by using Huawei's Ascend AI chips, the Shenzhen-based tech company's most advanced semiconductor series.
