The Chinese technology giant Huawei, which is threatened with losing the Android system due to US sanctions, presented on Friday a new operating system with which its mobile phones are equipped. The system, called “Harmonius,” was presented by CEO Richard Yu during a Huawei conference in Dongguan (south China). He said, "We want to bring more harmony to the world," while Huawei was placed on the American blacklist on suspicion of spying for Beijing. Huawei, the second smartphone group in the world, found itself in May in the midst of the trade war between Beijing and Washington against the backdrop of technological competition. Since 2012, Huawei has been seeking to have its own operating system.

On Thursday, China denounced the new rules announced by Washington on Wednesday evening, which prohibit the technology giant Huawei and other Chinese companies from signing contracts in American markets, and accused Washington of “abusive use of power.” These temporary rules will prevent any US federal agency from obtaining communications or technology equipment from these Chinese companies, starting on August 13. Huawei also faces a ban imposed on American companies for selling technological equipment. This ban is expected to come into effect in the middle of this month. Huawei announced that it will appeal these measures before the US Supreme Court.
