Policymakers will try to find common ground on key economic issues

Top of the agenda at the G7 meeting will be the effect of record oil prices on global trade imbalances and interest rate levels, analysts said.

The G7 are gathering on the sidelines of the International Monetary Fund (IMF) and World Bank spring meeting.

The IMF has called for more cooperation to ensure greater economic stability.

'Zero-sum gain'

"A disorderly unwinding of global imbalances would be very damaging and such an outcome becomes more likely as time passes and imbalances are left unaddressed," said Rodrigo Rato, the IMF's managing director.

"This is not a zero-sum game, but there is something to gain by all partners and the global economy if there is coordinated action," he continued.

The IMF is due to hold its first meeting on Friday morning, and the get together will continue behind closed doors over the weekend.

The G7, which is made up of the US, the UK, France, Germany, Japan, Canada and Italy, is scheduled to meet Friday afternoon.

One of the main topics for discussion will be imbalances in the world economy such as the size of the US trade deficit, with particular reference to the surge in exports from China.

President George W Bush met with Chinese President Hu Jintao on Thursday and urged him to allow the Chinese currency, the yuan to appreciate in value.

The US has accused China of keeping its currency artificially weak in order to boost exports, a key reason why the US trade deficit with China topped $202bn in 2005.

The US would like the IMF to play a more active part in this dispute by increasingly focusing on currency surveillance.
