BRUSSELS, Feb. 12 (Xinhua) -- European Union (EU) leaders on Thursday agreed to speed up efforts to strengthen the bloc's single market, with enhanced cooperation among at least nine member states possible if progress stalls, European Council President Antonio Costa and European Commission President Ursula von der Leyen said.
Speaking after an informal retreat of EU leaders in Brussels, Costa said there was broad consensus on advancing toward "one market for one Europe," underlining the urgency of the process and calling for concrete steps in 2026 and 2027.
