Huawei Technologies Co unveiled its new foldable smartphone, Mate X2, on Monday in an online launch event as the Chinese tech company showcased its technological prowess despite US government restrictions on its smartphone supply chains.

Priced from 17,999 yuan ($2,784) in China, Mate X2 features an inward-folding display and is powered by Huawei's in-house-designed Kirin 9000 5G chips. It was not immediately clear how much stock Huawei has for the new high-end foldable smartphone, as it is grappling with a shortage of chips due to Washington's restrictions.

But the premium phone still showcases the result of Huawei's years of pioneering research efforts. Yu Chengdong, CEO of Huawei's consumer business group, said the Mate X2 has a combination of cutting-edge hardware, innovative interaction and a thriving software application ecosystem.

Yu said starting in April, its in-house operating system HarmonyOS will be gradually expanded to its flagship smartphones, with the Mate X2 among the first batch to use the system.

The move will mark an important step for Huawei, which has been preparing for transition from Google's Android operating system to the self-developed HarmonyOS for a long time after the US government restricted its access to Google's software and services in 2018.

Meanwhile, "We are steadily increasing the production capacity for the Mate X2, in the hope of meeting consumers' demand," Yu said.
