HONG KONG/SHENZHEN/SHANGHAI, April 18 (Reuters) - C hinese technology giant Huawei started selling two models of its highly anticipated, high-end Pura 70 smartphone series on Thursday that many analysts expect to contain an advanced China-made chip like its Mate 60 handset.

The Pura series developed by the Shenzhen-headquartered company has advanced cameras and is known for its sleek design, while the Mate series emphasises performance and business features.

The launch of Huawei's Mate 60 series last year was celebrated by Chinese state media as a triumph over U.S. sanctions on the firm, as the handsets contain an advanced China-made chip that is considered only a few generations behind cutting-edge chips used by Western tech giants like Apple and Google in terms of computing power.

Eric Xu, Huawei's acting chairman, on Wednesday told a forum in Shenzhen that the company also plans to roll out a Mate 70 smartphone this year.

The Pro and Ultra versions of the Pura 70 were available on Thursday, while the Plus and base versions will begin sales on April 22. The phones were out of stock at Huawei's official online store just a minute after sales started, and hundreds of the brand's fans lined up at Huawei stores in Beijing, Shanghai and Shenzhen.

One customer, Lucas Zhuang, tested the network speed of the Pura 70 and said it was at the level of 5G. Washington has banned the licensing of 5G chips to China but Huawei's Mate 60 phones were already able to achieve 5G speed in many cases despite Huawei not branding it as 5G.

"We didn't know what chip the Pura 70 has inside. We only found out after we bought it," Zhuang, who already owns the Mate 60, told Reuters after waiting in line at Huawei's flagship store in Shanghai.

"But we believe ... the chip it has will certainly meet people's needs."

Ivan Lam, a senior analyst at research firm Counterpoint, said he expected shipments of about 60 million units from Huawei this year, with the Pura 70 series being an important catalyst. Last year, Huawei sold about 32 million smartphones.

"There may be some shortage at various channels but supply will be much better compared to when the Mate 60 was launched. We don't expect any longlasting shortage," he said.

The Pura 70 series has four variants: the 70, the 70 Plus, the 70 Pro and the 70 Ultra. The starting price for the Pura 70 series is 5,499 yuan ($760.06).

CHIP CHALLENGE

The launch of the Mate 60 Pro last August sparked a spike in Huawei's smartphone sales. According to Counterpoint, in the first six weeks of 2024, Huawei saw unit sales rise by 64% year-on-year. Meanwhile, Apple's iPhone sales in China fell 24% during the same period.

Huawei’s Kirin 9000S chip was reportedly manufactured by China's Semiconductor Manufacturing International Corporation (SMIC) despite U.S. export restrictions seeking to limit Beijing's chip-making capabilities.

It was seen as a symbol of China's technological resurgence despite Washington's ongoing efforts to cripple its capacity to produce advanced semiconductors.

The Biden administration began a review of the chip earlier this year and said last month that SMIC might have violated U.S. export rules, while adding it was still evaluating the situation.

Besides targeting China's chip manufacturers, the U.S. has imposed trade restrictions on Huawei since 2018, viewing the company and its products as a national security risk, which the company denies.

Elaborating on the pending Mate 70 smartphones on Tuesday, Xu said the goal is for it to use a "pure" version of its HarmonyOS operating system, developed in 2019 after U.S. sanctions cut Huawei's access to U.S. technologies such as Google's Android.

HarmonyOS had still been reliant on the Android application ecosystem but Huawei plans to cut that relationship and make HarmonyOS completely independent and able to compete with Apple's iOS and Android, he added.
