Chinese telecom giant Huawei unveiled its own operating system on Friday as it faces the threat of losing access to Android systems amid escalating US-China trade tensions.

Richard Yu, the head of Huawei’s consumer business, told a press conference in the southern city of Dongguan that the new system, called HarmonyOS or HongMeng in Chinese, would “bring more harmony and convenience to the world”.

The highly-anticipated software is considered crucial for the tech group’s survival as it confronts a looming White House ban on US companies selling technology products to Huawei which could remove its access to Google’s Android operating system.

Yu said the new system was a “future-oriented OS” to be “more smooth and secure”, which he said was “completely different from Android and iOS”.

Huawei said the first version of the operating system would launch later this year in its smart screen products, before expanding across a range of smart devices including wearable technology over the next three years.

“If you’re asking when will we apply this to the smartphone, we can do it at any time,” said Yu, adding that they gave priority to using Google’s Android operating system, which is compatible with Harmony.

“However, if we cannot use it (Android) in the future, we can immediately switch to the Harmony OS,” he said.

In May the company was swept into the deepening trade war between Beijing and Washington which has seen punitive tariffs slapped on billions of dollars of two-way trade.

Huawei — considered the world leader in superfast fifth-generation or 5G equipment and the world’s number two smartphone producer — has been blacklisted by US President Donald Trump amid suspicions it provides a backdoor for Chinese intelligence services, something the firm denies.
