The Group of Eight (G-8) concluded its three-day annual meeting Thursday afternoon as US President George W. Bush called the summit "a very successful meeting."

As one of the most important achievement, the G-8 summit, held at Sea Island in Georgia State from June 8 to June 10, on Wednesday adopted the "Partnership for Progress and a Common Future With the Region of the Broader Middle East and North Africa" to promote democratic, economic and social reforms in the Middle East countries, and stressed the need of resolving the Israeli-Palestinian conflict for any progress in the Middle East.

The leaders of the G-8 summit issued a statement on Thursday calling on the quartet, composed of the United Nations, the United States, Russia and the European Union, to meet this month to revive the stalled Roadmap plan for the Middle East peace process.

"The G-8 views the quartet Roadmap as the way forward towards a comprehensive settlement and call on all parties to abide by their obligations under the Roadmap," the G-8 summit said in a statement.

"The G-8 countries will join with others in the international community, led by the Quartet, to restore momentum on the Roadmap," the statement said.

"The G-8 calls upon the Quartet to meet in the region before the end of this month, engage with Israeli and Palestinian representatives and set out its plans for taking forward in practical terms its declaration of May 4," the statement said.

"The G-8 hopes that this disengagement initiative will stimulate progress towards peace in the region, the realization of Palestinian national aspirations and the achievement of our common objective of two states, Israel and a viable, democratic, sovereign and contiguous Palestine, living side by side in peace and security," the statement said.

During the three-day meeting, the G-8 summit also achieved progress on issues such as nonproliferation, war on terror, travel safety and trade.

As to the role of NATO in Iraq, Bush retreated from his speaking during the summit that NATO ought to be involved in Iraq.

At the conclusion of the G-8 summit on Thursday, Bush said that he does not expect more troops from NATO in Iraq, after France and Germany refused clearly to send troops to Iraq.

Also on Thursday, British Prime Minister Tony Blair said that disagreements over a possible wider NATO role in Iraq among the leaders of the G-8 would be eventually resolved.

"I am not quite sure where this disagreement has surfaced, but I think the disagreement will be overcome," Blair said at a news conference on the sidelines of the G-8 summit.

Meanwhile, Blair admitted that a large number of NATO troops in Iraq was not practical.

As to the next G-8 summit, Blair said that "I look forward to hosting the G-8 next year" at the luxurious Gleneagles Hotel in Scotland.
