US President Donald Trump has promised a new security deal for Ukraine that “might involve all of Europe,” after meeting a top Russian envoy on Thursday – but the proposal has few details and left European capitals puzzled.

“It’s going to be a very big. It’s going to involve more than Ukraine, and I could even say it might involve all of Europe. It’s going to be a big, beautiful agreement, and everyone’s going to be thrilled,” Trump told reporters on Thursday, without going into any details.
