Group of Eight (G8) leaders aim to present a united front against global inflation, driven by soaring oil and food prices, at a summit in Japan next week, but solving the problem requires more than just a strong message from rich nations.
As record high oil prices threaten the global economy and food riots undermine political stability in some countries, the G8 will try to draw up measures to balance the supply and demand of oil, officials from member countries said.
It will also aim for closer co-operation with oil producers.
When leaders from the G8 - the US, Britain, Canada, France, Germany, Italy, Japan and Russia - gather at the July 7-9 summit in Hokkaido, northern Japan, they will discuss concerns that a weaker dollar is a factor behind high oil prices.
But with finance ministers and central bankers absent, they will probably make little headway.
A German government source said while inflation was on the agenda, the G8 chiefs would not make interest rate recommendations to central banks.
'It is being questioned what kind of a message we will be able to send on rising oil prices,' said Japan's Deputy Foreign Minister Masaharu Kohno.
He added that 'there may not be a revolutionary panacea' for solving the problem of surging oil prices which hit a record high of $145.85 on Thursday.
The German source agreed, saying G8 leaders were not in a position to reverse the trend of high prices. But the source believes a clear statement would help.
Analysts said a show of concern by the G8 would not be enough to ease global inflation, which took the centre stage just as the world economy was starting to recover from the credit crisis.
'The summit faces unprecedented challenges amid signs of stagflation, which had not been seen in 30 years,' said Kyohei Morita, chief economist at Barclays Capital Japan.
'But there is a mismatch between the themes of the summit and who is participating, making it hard to actually implement any concrete and effective steps,' he said.
He noted that Opec oil producers and Southeast Asian couterparts, whose trade restrictions helped push up commodity prices, would not be joining the G8 summit.
