SHENZHEN, China, June 21 (Reuters) - China's Huawei Technologies said on Friday it had made breakthroughs in fields from operating systems to artificial intelligence, and that it had taken the company 10 years to do what the United States and Europe took 30 years to achieve.

Richard Yu, chairman of Huawei's Consumer Business Group, was speaking at the opening of a three-day developer conference in the southern Chinese city of Dongguan, where he said the company's Harmony operating system was now available on more than 900 million devices.

"Harmony has made major breakthroughs. You can say in 10 years we've achieved what it took our European and American counterparts more than 30 years to do, in terms of building the core technology of an independent operating system," Yu said.

The company's Ascend artificial intelligence infrastructure - the most powerful from a Chinese company - was now the second most popular after Nvidia, which dominates the market for AI chips, Yu added.

Operating systems and other software has been dominated by Europe and the United States for a long time, although the era of internet of things has given Huawei an opportunity to overtake them, he said.

In the first quarter of 2024, Huawei's HarmonyOS, its in-house version of the operating system, surpassed Apple's iOS to become the second best-selling mobile operating system in China behind Android with a 17% market share, research firm Counterpoint said.
