A court filing from Monday reveals that banned Chinese tech leader Huawei has dropped a lawsuit against the US government following the release of its seized telecom equipment. The US government had previously confiscated Huawei’s telecom equipment over suspicions that the company had violated export controls.

However, Huawei has now confirmed that the US government released the seized equipment after two years in August after evaluating and confirming that no export license was needed for it. Huawei has expressed its disappointment in the court filing in the government failing to provide an adequate explanation for detaining the equipment.

Amid escalating trade tenions with China, the US government had added Huawei to a trade blacklist, the Entity List, in May 2019. Washington alleges that the Chinese government uses Huawei’s technology to spy on international governments and citizens. As a result of this move, Huawei has been unable to procure technology and components from American companies without special approvals from the US government.
