BEIJING — Huawei said on Wednesday that its sales growth recovered in the most recent quarter, suggesting that the Chinese technology giant has been successfully weathering the Trump administration’s efforts to stymie its business around the world.

The United States added Huawei to an export blacklist in May, restricting its access to many of the American-origin parts it needs to make its smartphones and telecom gear and causing the company’s revenue growth to take a hit. But sales from January to September were $86 billion, an increase of nearly 25 percent from a year earlier, Huawei said. That implies, based on comparisons with previously released figures, that sales accelerated in the July-to-September quarter.

Huawei is the world’s leading producer of the equipment that powers cellphone networks. But American officials have long been concerned that the Chinese government could use the company’s products to gather intelligence, an accusation that Huawei has repeatedly denied.

Washington’s warnings have so far failed to halt Huawei’s drive to remain a powerhouse supplier as telecom carriers around the world upgrade their networks to the next generation of wireless technology, or 5G. The company said on Wednesday that it had signed more than 60 5G contracts worldwide, up from 50 a few months ago.
