Protecting the Ukrainian sky is "our priority #1 and topic #1 at #Ramstein 7", Ukrainian Defence Minister Oleksiy Reznikov has said on Twitter.
The seventh meeting of the Ukraine Defence Contact Group (known as Ramstein) is being held today.
"Together with our partners we're working on an integrated & echeloned air defense system.
We are preparing for winter on the battlefield," he tweeted.
He thanked US Secretary of Defense Lloyd Austin for "leading the international coalition against evil".
