Ukrainian President Volodymyr Zelenskyy said on Monday the United States was preparing an aid package worth $800 million to finance production of Ukrainian drones, Paralel.Az reports citing Reuters.

Zelenskyy, in his nightly video address, said the package was in addition to a $400 million package for new arms announced during U.S. Defense Secretary Lloyd Austin's visit to Kyiv.

"A separate package is also being prepared -- $800 million in funding for the production of Ukrainian drones," Zelenskyy said.

"Ukraine is grateful for this. We need to ensure that, whatever the political threats in the world, Ukraine can consistently defend its sovereignty and independence."

Zelenskyy told a meeting with foreign arms manufacturers this month that Ukraine could produce four million drones annually and was quickly ramping up its production of other weapons.

He said Ukraine had already contracted to produce 1.5 million drones this year.
