British Prime Minister Gordon Brown will discuss global financial supervision and co-ordinated measures to support the economy with US President Barack Obama this week.
Mr Brown will become the first European leader to meet the US president, in Washington on Tuesday, since Obama's inauguration in January.
"I believe there is no challenge so great or so difficult that it cannot be overcome by America, Britain and the world working together," Mr Brown wrote in a Sunday newspaper.
"That is why President Obama and I will discuss this week a global new deal, whose impact can stretch from the villages of Africa to reforming the financial institutions of London and New York, and giving security to the hard-working families in every country."
Mr Brown said the two countries' historic "partnership of purpose" should be directed at fighting the economic downturn as well as terrorism, poverty and disease.
Britain is keen to get U.S. support for the bold aims of a G20 summit of advanced and developing nations to be held in London on April 2nd.
Mr Brown last met Mr Obama in London last year when the US leader left the presidential campaign to tour several European capitals to show off his foreign policy credentials.
