From free trade to Greece: What's on the agenda at the EU summit

European Union heads of state and government are meeting in Brussels on Thursday and Friday to talk about economic and energy policies, and the crises in Ukraine and Libya. A special meeting has also been arranged to discuss the Greek debt problem.

Here are the main issues on the agenda:

— GREECE: A mini-summit will take place Thursday evening with Greek Prime Minister Alexis Tsipras to discuss Greece's precarious financial situation. German Chancellor Angela Merkel has said she doesn't expect a breakthrough.

— UKRAINE: Leaders will discuss how Ukraine and pro-Russian rebels are implementing peace accords for eastern Ukraine. Further sanctions against Russia are not on the agenda.

— FREE TRADE: Amid growing opposition, the leaders will encourage the European Commission to try to reach a free trade pact with the United States. Many Europeans fear it will harm workers and consumers.

— ENERGY UNION: Europe wants to end the separation between its 28 national energy markets. The EU estimates this might save European consumers some 40 billion euros ($42.7 billion) a year.

— ECONOMY: European leaders are talking with the head of the European Central Bank, Mario Draghi, about how to spur growth. A new program aims to raise investment by 315 billion euros.

— LIBYA: EU members have been debating the possibility of a peacekeeping operation. The oil-rich North African nation has become a target for groups such the Islamic State.
