Huawei Technologies on Monday showcased a series of new products from a gold smartwatch to a smart car but disappointed viewers by not revealing more details about its new Mate 60 smartphone series, prompting an outpouring of complaints online. The event, held in a stadium and watched by millions online, was expected to see Huawei break its silence on the smartphone, which has been hailed by Chinese state media as a sign the firm had overcome US sanctions that since 2019 has cut its access to advanced chipmaking tools and crippled its smartphone unit, Reuters reported.
