Citing national security, US lawmakers are looking to ban military purchases of Chinese-made drones—which could boost prospects for US makers struggling to compete, said the Wall Street Journal.

The US National Defense Authorization Act passed by the Senate last week would bar Chinese drones for military use as US officials grow worried that the country’s reliance on Chinese drones may be putting critical US infrastructure at risk

Government officials are concerned the drones may be sending information back to the Chinese government or hackers elsewhere to use for cyberattacks or other offenses.The House version of the bill, expected to get a vote this month, would ban foreign drones.

The Pentagon last year banned purchases of commercial, off-the-shelf drones until it can determine how to mitigate security risks, including when drones are used for surveillance of military installations and critical infrastructure.
