Chinese smartphone manufacturer ZTE was recently banned from selling its devices in the US for allegedly breaking a trade embargo on Iran, and US companies were ordered not to trade with the company for seven years. While ZTE plans to fight the imposed sanctions, another Chinese manufacturer, Huawei, is now facing an investigation for allegedly violating Iran sanctions.

When asked about the matter, Zhao Ming, president of Huawei’s sub-brand Honor, said:

Developing an alternative OS has become one of the top priorities for Huawei, after the recent escalation of trade disputes between the US and China. The company is now under investigation by US authorities for alleged violations of sanctions which banned sales to Iran. As of now, neither the US Department of Justice nor Huawei have confirmed that the investigations are taking place.
