China's Huawei unveils triple-folding phone

Chinese tech giant Huawei on Tuesday unveiled its new smartphone, billed as the world's first trifold phone, just hours after US competitor Apple lifted the curtain on its new iPhone built for AI.

The Mate XT was officially launched in a keynote presentation by Huawei executive Richard Yu at the firm's headquarters in the southern city of Shenzhen. It goes on sale on September 20.
