The Bulgarian Ministry of Environment and Water (MOEW) has stated that the country cannot provide long-term guarantees for specific volumes of water to Greece, citing climate uncertainty, declining river runoff, and increasing domestic demand as key limiting factors. The position was issued in response to comments by Greek Prime Minister Kyriakos Mitsotakis, who called for a long-term bilateral arrangement on transboundary waters, including flows from the Arda and Maritsa rivers.
