Guests have their faces scanned at the World Artificial Intelligence Conference in Shanghai in August, 2019.

BEIJING — China struck a confident tone Tuesday in the face of new challenges from the U.S. to Chinese technological development.

Amid ongoing trade tensions between the two countries, U.S. President Donald Trump's administration this year placed Chinese telecommunications giant Huawei — along with some supercomputing firms and some major artificial intelligence companies — on a blacklist. The so-called "entity list" effectively prevents those businesses from buying from their American suppliers.

"Overall (the list) cannot hurt the fundamentals of China's technological development," said Huang Libin, spokesman and director general of the performance inspection and coordination bureau, of China's Ministry of Industry and Information Technology.
