WASHINGTON, Sept 5 (Reuters) - The Trump administration

plans to issue rules to restrict or potentially bar imports of

Chinese drones and medium and heavy-duty vehicles after an

earlier crackdown on cars and trucks, citing national security

concerns.

The U.S. Commerce Department on Friday said it plans to

issue rules as soon as this month to address national security

risks involving information and communications technology that

is integral to drones and their supply chain, as well as

vehicles weighing more than 10,000 pounds from countries like

China and other foreign adversaries.

It did not give details on what the import rules would be.

The Commerce Department and Chinese Embassy in Washington

did not immediately comment.

Chinese imports account for the vast majority of U.S.

commercial drone sales. More than half come from DJI, the

world's largest drone manufacturer.

The planned restrictions on drones and heavy-duty vehicles

follow on from similar rules already scheduled on imports of

cars and other trucks.

Democratic former President Joe Biden's administration

finalized rules in January that will effectively bar nearly all

Chinese cars and trucks from the U.S. market starting in late

2026, as part of a crackdown on vehicle software and hardware

from China.

The Commerce Department in January said it could also

target for restrictions drone systems like onboard computers,

communications and flight control systems, ground control

stations, operating software and data storage.

The department opened national security investigations

into the import of drones and related components in July and

into medium and heavy duty vehicles and parts in April, which

could lead to higher tariffs.

U.S. President Donald Trump in June signed executive

orders to bolster defenses against threatening drones and to

boost U.S. drone manufacturing.

In December, Biden signed legislation that could

eventually ban DJI and Autel from selling new drone

models in the United States.
