US president Barack Obama has invited 16 "major economies" including the European Union and the United Nations to take part in a forum on climate change to facilitate a UN pact on global warming.
Mr Obama, who has taken a more aggressive stance on climate change than his predecessor George W. Bush, last night invited the group to a preparatory session on April 27th and 28th in Washington.
The White House made clear that Mr Obama's new initiative would aim to augment UN talks that are meant to culminate in an agreement in Copenhagen in December.
"Our goal is to use this forum very much as a key part in how we reach an overall agreement," a senior administration official said, adding the review was "an important piece of the puzzle of how we get from here to Copenhagen."
The "Major Economies Forum on Energy and Climate" has echoes of a similar set of meetings organised by the previous administration.
Mr Bush's "major economies" initiative drew skepticism from participants, who were wary the process was his administration's way of circumventing broader UN talks to forge an international deal.
The US official said countries around the world had expressed interest in restarting the major economies process because of Mr Obama's differences from Mr Bush on climate change. The president, who took office in January, has said he wants the United States to take the lead in global warming talks.
The April meeting, to be hosted at the State Department, would likely touch on a range of issues including technology, financing, and emissions trading, the official said.
In a statement, the White House said the forum would "help generate the political leadership necessary" to achieve an international pact to cut greenhouse gas emissions later this year.
It said the meeting would spur dialogue among developed and developing countries about the issue, "and advance the exploration of concrete initiatives and joint ventures that increase the supply of clean energy while cutting greenhouse gas emissions."
The major economies include: Australia; Brazil; the UK; Canada; China; the European Union; France; Germany; India; Indonesia; Italy; Japan; Korea; Mexico; Russia; South Africa and the United States.
Denmark, which is hosting the UN meeting in December to forge a pact that would take over from the Kyoto Protocol, was also invited.
Mr Obama's announcement comes shortly before a fresh round of UN climate talks began in Bonn today. Up to 190 countries are meeting to work on plugging huge gaps in the international pact, which is slated to be agreed to in Denmark in December.
Mr Obama wants to cut US emissions by roughly 15 per cent back to 1990 levels by 2020. Mr Bush saw US emissions peaking as late as 2025.
