Group of Seven policymakers need to be alert to the persistence of global economic imbalances and high energy prices, British Finance Minister Gordon Brown said in an interview.
G7 finance ministers and central bankers are due to meet in Washington next month at the Spring meetings of the International Monetary Fund and World Bank.
Mr Brown, who chairs the IMF's main policy steering group said he expected the world economy to "grow well" this year but said there remained risks to the outlook.
"We have got to be continuously vigilant. There are imbalances in the world economy and we still have the instability that has come from very high oil and energy prices and indeed rising commodity prices," he said.
One of policymakers' biggest worries in recent years has been the size of the US current account deficit and the G7 has wanted China to let its currency rise further against the dollar in the hope that this would reduce America's trade gap.
Mr Brown delivered his 10th annual budget last Wednesday and many say it could be his last as the clamour for him to replace Prime Minister Tony Blair has been getting stronger.
Mr Blair has said he will not fight another election but has been under pressure to hasten his departure after it was revealed rich businessmen were nominated for seats in the upper house of Parliament after lending the Labour party large sums of money. Mr Brown said he had not known about the loans.
"I've never been involved in party political funding and because as Chancellor I've got to deal with businesses on a day-to-day basis," he said.
But the Labour party's heir apparent sidestepped the issue of when he would succeed Mr Blair.
"I have always said that every budget could be your last if you don't get it right," Mr Brown said. "And I hope this is the right budget for Britain." The budget contained few surprises on the economic side but Mr Brown offered a number of giveaways to help the elderly, parents and first-time home buyers, though at little overall extra cost to the exchequer.
Mr Brown also announced extra money for education with the aim of ensuring that pupils at state-run schools had the same quality of teaching as those in the private sector.
But opposition politicians hit back, accusing him of neglecting the state-funded National Health Service.
Mr Brown said this was not the case.
"We are focussing more on education but we are also continuing to spend six billion pounds more on the health service," he said.
