"German Chancellor Angela Merkel is traveling to Washington this week to discuss the financial crisis and climate change with US President Barack Obama -- two issues where Germany and the US are deeply divided...

"When US President Barack Obama recently met with German Chancellor Angela Merkel in Dresden, he... remained true to the program at first. But then he unexpectedly asked 'Angela' why, exactly, she didn't want Turkey to be accepted into the European Union. Merkel was taken aback. She had to think on her feet and quickly come up with an answer for an issue on which she had no pre-prepared comments. It became clear to her, once again, that this president is a challenge, both for Merkel and for German politics as a whole...

"A clash of cultures is raging between Berlin and the United States on the issue of financial policy... The German chancellor... considers the Americans' offensive monetary policy to be dangerous... A few hours after the encounter between Merkel and Obama, Ben LaBolt, a White House press spokesman, told a colleague about the difficult relationship between the two leaders. 'They are not getting any warmer,' he said...

"Obama's visits to Dresden and Buchenwald also ruffled some feathers in Germany. The US president's advance team, which had been sent to help prepare for the trip, made a negative impression on the Germans through their coarse language and overbearing behavior. German officials were shouted at, treated like schoolchildren and told to wait their turns... As it is, the US president in person is by no means the charming and smiling character many have come to expect from his television appearances. He cultivates a cool style or, as one of the members of the delegation describes it, 'an almost unfeeling style.'"

"Ms Merkel arrives in Washington on Thursday and meets Mr Obama on Friday. It will be their third meeting in less than a year. Ms Merkel hosted the US president in Dresden three weeks ago. Yet in spite of frequent meetings and delight among Germans at Mr Obama’s election, the rapport between the old allies has deteriorated in recent months... 'The chancellor is not interested in joining the competition for who gets along best with Obama,' a senior aide said on Wednesday...

"Economic policy is not the only source of tension. While Berlin has long been critical of the prison at Guantánamo Bay, it has rejected US requests to take detainees. It has also dragged its feet on committing troops to Afghanistan... Other matters have conspired to poison the atmosphere. German officials said last month the US Treasury’s role in talks between Berlin and General Motors over the future of Opel, its German arm, had been offhand and unhelpful.

"While Mr Obama had only planned to tour the Buchenwald concentration camp during what had been billed as a private visit this month, Ms Merkel insisted he go to Dresden, the Baroque city razed by US and UK bombers in 1945. Their first clash goes back before Mr Obama’s election last summer, when Ms Merkel vetoed his plan to make a speech before the Brandenburg gate. The address was moved a mile west to the victory column."
