WASHINGTON, May 21 (Xinhua) -- Chinese drone maker DJI on Tuesday denied U.S. accusations that Chinese-made drones are hacking sensitive flight data of their customers.

This came after the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued a warning that Chinese-made drones contain components that collect operation and customer data for intelligence use.

CISA has released an industry alert on "the inherent risks associated with using UAS (unmanned aircraft system) technology manufactured in China," a spokesman for CISA told Xinhua in a statement on Tuesday.

A DJI spokesman told Xinhua on Tuesday that the company gives all customers full and complete control over how their data is collected, stored and transmitted.

"For government and critical infrastructure customers that require additional assurances, we provide drones that do not transfer data to DJI or via the internet, and our customers can enable all the precautions the Department of Homeland Security recommends," a DJI statement said.

The Chinese drone manufacturer holds more than 70 percent of the worldwide civil drone market share, according to Skylogic Research, a drone analyst company.
