The United States will evaluate demands made by Russia after Moscow had agreed "in principle" to a U.S.-brokered ceasefire with Ukraine in the Black Sea to allow safe navigation, U.S. Secretary of State Marco Rubio said on Wednesday.

The White House said Tuesday that both Ukraine and Russia have agreed to stop using force in the Black Sea – a deal in principle that the Kremlin says comes with several conditions before it can be implemented.

The relations between Ukraine and the United States have returned to normal after the spat between Volodymyr Zelenskyy and Donald Trump at the White House, states the head of the President's Office, Andriy Yermak in an interview with Reuters.
