BEIJING: Struggling under U.S. sanctions, Huawei<\/a> unveiled a folding smartphone with an 8-inch (20-centimeter) -wide screen Monday to show off its tech prowess but said it will be sold only in China.

The Mate X2 highlights the challenges for Huawei Technologies Ltd. after Washington cut off access to U.S. processor chips and Google<\/a> services. Last year, Huawei fell from the top-selling global smartphone brand to sixth place.

Huawei says the Mate X2, its third folding phone, has crisper visuals and better sound for movies and games. It runs on Huawei's most advanced processor chip, the Kirin<\/a> 9000.

The phone offers \"a truly immersive experience,\" the president of Huawei's consumer unit, Richard Yu, said at a launch event broadcast online.

Huawei, China's first global tech brand, was battered by being put on an export blacklist by then-President Donald Trump in 2019 as a security risk, an accusation the company denies. Huawei sold its budget-priced Honor smartphone brand in November to focus resources on higher-end models.

The Mate X2 will start at 17,999 yuan ($2,785), according to Yu.

Monday's launch \"says a lot about how it still wants to trumpet its advances in technology, even if commercially speaking, its shipments will be severely hampered,\" said Bryan Ma of IDC in an email.

Executives said earlier Huawei stockpiled chips and other components in preparation for a possible U.S. cutoff. It isn't clear how long those supplies might last.

Huawei designed the Kirin line that powers its most advanced smartphones but relies on outside manufacturers including Taiwan's TSMC<\/a> to make them.

The Trump administration stepped up sanctions last year by blocking TSMC and other global producers from using U.S. technology to make chips for Huawei, including those designed by the company.
