Washington insisted Saturday that its Ukraine proposal is indeed official US policy, denying claims by a group of senators that Secretary of State Marco Rubio told them the document under discussion is just a Russian “wish list.”

The dispute over the 28-point plan — which cedes Ukrainian territory long sought by Moscow — threw an extraordinary element of confusion into efforts to negotiate an end to the war.

US President Donald Trump has pushed the plan, pressuring the Ukrainians to accept it within days. Negotiators will meet in Switzerland on Sunday.

However, after a storm of criticism that the proposal is almost entirely favorable to Moscow, several US senators spoke out, holding a press conference at the Halifax International Security Forum in Nova Scotia, Canada on Saturday. (AFP)
