President Barack Obama had more success with former Cold War combatants than with some European allies as the Group of 20 summit of world leaders began, starting new talks on arms and trade with Russia and China but facing a challenge from France and Germany over economic leadership. Mr. Obama began by conceding U.S. culpability in starting the global financial crisis, but also called on Europe and others to do more to end it, in an opening news conference with the summit host, British Prime Minister Gordon Brown. French President Nicolas Sarkozy and German Chancellor Angela Merkel answered just hours later with a combative appearance of their own, demanding fast and strict international regulation of the world financial system; Mr. Sarkozy called it "nonnegotiable.
Disagreements between the European Union and the US over how to combat the global recession widened on Tuesday as EU governments made clear they had little appetite for piling up more debt to fight the collapse in output and jobs. Finance ministers from the 27-nation bloc insisted in Brussels that it was doing enough to support world demand and did not need at present to adopt another fiscal stimulus plan, as Washington is urging.
The US-European differences are casting a shadow over next month’s summit in London of leaders from the G20 group of advanced and emerging economies, an event to be attended by Barack Obama on his first visit to Europe as US president.
