WASHINGTON (Reuters) - The U.S. government is stopping imports of some DJI drones from entering the United States, the Chinese drone maker told Reuters on Wednesday.

In a letter seen by Reuters, DJI notified distributors that U.S. Customs and Border Protection is citing the Uyghur Forced Labor Prevention Act in withholding some drones from being imported into the United States.

The company said no forced labor is involved at any stage of its manufacturing process but added the law "gives them the authority to withhold goods without any tangible evidence."

DJI told Reuters it is proactively engaging with Customs and providing documentation that verifies its compliance with the law known as UFLPA.
