The wikipedia has "Building upon these bilateral discussions aiming at creating a hard core of allies in Europe focused on Ukraine and wider European security..."
Allies isn't being used in terms of Alliance here. I don't know the full list but most of the countries on that list, and perhaps all, are already allies. There's nothing to further ally about.
What this is, is a cooperation framework toward a shared purpose. None of those countries are abandoning or being abandoned by the United States as an ally, nor are any of those countries creating new alliances with each other.
I know there's this gut reaction on the Internet to act like the rest of the world is banding together and leaving the United States because of President Trump or something, but it's just not the case. At the end of the day, the only country in the world that has military and industrial power to defend against Russia or China today is the United States. That's not a slight at Japan, or France, or anything like that, but an acknowledgment of reality.
President Trump's administration has been, in my view, haphazard and stupid in how it has treated out allies and partners in many ways. In some ways they've been correct though too, and it's important to not overreact to news headlines.
I guess it depends how you define things.
