The European Union should "renew and intensify" its diplomatic engagement with countries that still maintain close ties with Russia in a bid to increase the pressure on the Kremlin to accept a 30-day unconditional ceasefire in Ukraine, a group of 15 member states has said in a joint letter to High Representative Kaja Kallas.
The suggestion comes after last week's face-to-face, low-level talks between Kyiv and Moscow envoys failed to deliver progress on the ceasefire proposal, which has been firmly backed by the "Coalition of the Willing" and the United States.
