Huawei has finally unveiled Harmony OS, the operating system it was rumoured to be working on that could replace Android on its smartphones and tablets. The operating system has been long rumoured to be called Hongmeng, which is what it will be known as in China.

The company has had to accelerate the development of Harmony since the US government heightened the negative perception of Huawei in the west by adding it to the Entity List, resulting in a temporary ban in trading with Google. Today at Huawei’s developer conference, Harmony OS was officially announced, though it isn’t immediately clear if it will be used as a direct Android competitor.

In a tweet, it suggests that Harmony OS is designed to act as a system that better ties together connected devices as opposed to a singular operating system for one kind of device.

It looked recently like things were cooling after Trump indicated at a G20 meeting that US companies were again free to trade with Huawei. But a Bloomberg report yesterday suggests that the US will again halt the progess with Huawei after China stopped US crop buying as a result of a new tariff threat.

It’s a big old mess in the US-China trade war and it’s Huawei that’s caught up in the middle. For now, the company is pressing ahead by officially announcing Harmony OS, but time will tell if it has to result to using it on all of its devices.
