HEILIGENDAMM, Germany — The leaders of the Group of Eight ended their summit Friday after agreeing to set a non-binding goal to cut greenhouse gases, warn Iran over its nuclear programme, and give $60 billion to fight AIDS, TB and malaria in Africa.A deal on the future of Serbia’s Kosovo province eluded them, however.

The host, German Chancellor Angela Merkel, pronounced the summit a success after getting what she most wanted: US agreement to a statement that at least mentions a fixed cut in greenhouse gas emissions, even if it lacks a binding commitment.

“Naturally, after two days, all of the problems of the world have not yet been solved. But we have moved a step forward,” Merkel said as she wound up the meeting of leaders from Germany, the United States, Russia, Japan, Britain, Italy, France and Canada.

Among the many decisions yesterday by the eight leaders was a promise to spend billions more on fighting AIDS, tuberculosis and malaria in Africa. The $60 billion promise remained vague, spread over “the coming years” without a specific timeframe, and some aid groups said it was additionally diminished because it is money already promised. Some $30 billion would come from the US over five years.

After meeting with African leaders, the G-8 also promised to fulfil a pledge made at the 2005 summit to increase aid to Africa by $25 billion a year by 2010. Anti-poverty campaigners have complained the countries are falling behind on that promise.

Bob Geldof, who nurtured the Live Aid concert in 1985 and the series of Live 8 concerts in 2005, seethed, calling the summit a “grotesque pantomime.”

“Do me a favour, get serious guys, get serious,” he said. “This wasn’t serious. This was a farce. A total farce.”

In Africa, an array of aid groups and African academics said the declaration fell short of the goals unveiled at a G-8 summit two years ago.

“Even this $60 billion smoke screen can’t cover up for the abject failure of the G-8 to move forward on their AIDS promises,” said Aditi Sharma, head of the HIV/AIDS campaign for South Africa-based ActionAid.

The G-8 aimed a warning at Iran, underlining support for more measures against Tehran if it does not halt uranium enrichment, obey UN resolutions and return to talks. Efforts are under way in the UN Security Council to impose more sanctions.

Merkel said Iranian President Mahmoud Ahmadinejad’s recent anti-Israel comments were one of the reasons the group adopted such a forceful resolution.

“I find that the statements of the Iranian president about Israel are fully unacceptable,” she said.

French President Nicolas Sarkozy said the G-8 thought it was necessary to “send a message of firmness, certainly a toughening of sanctions.”

The leaders — also including Russia’s Vladimir Putin, Italy’s Romano Prodi, Britain’s Tony Blair, Japan’s Shinzo Abe and Canada’s Stephen Harper — held their final sessions at the Baltic Sea resort of Heiligendamm without President Bush, who stayed in his room to recuperate from an upset stomach after meeting privately with Sarkozy.

Bush soon was feeling better and rejoined the summit after missing a session with African leaders and part of another with heads of state from China, India, Brazil, Mexico and South Africa.

There was an unscripted moment when a protester hurled opposition leaflets during a news conference by Putin, who said: “Excellent, well done,” asked for a leaflet and kept talking.

Despite deals on climate change, Iran and Africa, no deal was reached on Kosovo, despite talks among deputies late into the night Thursday.

The United States and key European governments back a UN resolution that would grant the predominantly ethnic Albanian province of Serbia supervised independence. Kosovo has been under UN supervision since a NATO-led air war in 1999 to halt a Serbian crackdown on ethnic Albanian separatists.

Serbia considers Kosovo its historic heartland, and has resisted ceding the province. The Russians, Serbia’s traditional ally, say they oppose any solution imposed over Belgrade’s objections.

Sarkozy proposed a solution that would require Russia to recognise Kosovo’s eventual independence. Then, there would be a six-month wait, during which Belgrade and the Kosovo Albanians would hold talks. If they reach no agreement, the UN plan would then take effect.

“Regarding Kosovo, there has been no movement,” Sarkozy said. “For a simple reason, it is not possible to give Belgrade and Pristina time to continue talks, considering that our Russian friends consider that Kosovo’s independence is an unacceptable condition. It is a condition of an agreement.”

Diplomats will meet next week to discuss the proposal.

The G-8 leaders adopted a statement Thursday that said they should “seriously consider” proposals to cut the emissions of greenhouse gases by 50 percent by 2050. The language is a compromise between the European Union, which wants mandatory cuts, and the United States, which opposes them.

Several environmental groups called it a fudge. Others said it was progress.

Prodi, calling the summit a success, said that “the US position has come closer to that of Europe on climate change with official recognition that the problem is large, serious and urgent and that it must be confronted on a global level and therefore within the framework of the United Nations.”
