FACTBOX: Participants and agenda of G8 summit in Italy

(Reuters) - Leaders from the Group of Eight major industrial nations and the main developing economies will hold talks from July 8-10 in the central Italian city of L'Aquila.

Italian Prime Minister Silvio Berlusconi says it will group leaders representing 90 percent of the global economy, with 40 countries and international organizations expected to attend.

Following are details on the agenda and the participants attending the summit:

WEDNESDAY, JULY 8TH

G8 - The first day of the meeting will group the leaders of the Group of Eight nations -- United States, Britain, Germany, Italy, France, Russia, Canada and Japan -- plus European Commission President Jose Manuel Barroso and current EU president Sweden.

They will issue a statement on the situation of the world economy, exit strategies from the financial crisis, climate change and development, particularly in Africa. They will discuss a charter for global financial regulation, dubbed "global standards" by the Italian presidency.

There will be a separate political statement following a dinner for G8 heads of government, expected to mention the situation in the Middle East, Iran, North Korea, piracy off Somalia, terrorism and nuclear proliferation.

G5 - Separately, the leaders of the Group of Five nations -- China, India, Brazil, South Africa and Mexico -- are due to hold parallel talks on the first day and issue a statement.

THURSDAY, JULY 9TH

G14 - The Group of Eight and Group of Five will hold joint talks, with Egypt attending as special guest of the Italian presidency.

A first joint statement by the two groups, dubbed the G14, is expected to focus on the response to the financial crisis, efforts to break a deadlock in the Doha Round of world trade negotiations, and relations between the two groups.

At the request of China, the G14 may discuss proposals for a new global reserve currency as an alternative to the dollar.

MAJOR ECONOMIES FORUM (MEF) - Thursday will also see a meeting of U.S. President Barack Obama's initiative to tackle climate change, the 17-member Major Economies Forum (MEF).

This includes the G8 and the G5, as well as Australia, Indonesia, South Korea and the European Union. Its members account for roughly three quarters of global emissions.

The United Nations will also attend the talks, while Denmark will attend as the host of December's U.N. climate change talks in Copenhagen. The MEF will issue a statement on climate change.
