LONDON, July 15 (Xinhua) -- European Commission President Jose Manuel Barroso is worried the EU-U.S. relationship is not fulfilling its potential, according to a report in The Times Thursday.
In an interview, Barroso told the paper the new era at the White House was in danger of becoming a "missed opportunity" for Europe.
The president said: "The transatlantic relationship is not living up to its potential. I think we should do much more together. We have conditions like we have never had before and it would be a pity if we missed the opportunity."
The criticism follows a series of fundamental disagreements at the G20 summit on how to deal with the economic crisis, climate change and trade reform.
British Prime Minister David Cameron is expected to visit the United States on July 20. Downing Street said the relationship between Europe and America had always been built on dialogue and cooperation.
"If Mr Barroso thinks that we should see more of that, we'd agree," Downing Street sources said.
Barroso said: "Of course, it is a question of how the Americans are going to reach out to us as well because the relationship should be perceived as mutual."
However, the United States defended itself forcefully against claims that it had neglected Europe.
The view from Washington is that communication with Europe on a range of crucial issues is difficult because the EU still lacks "a clear foreign policy apparatus."
The Times quoted a senior U.S. figure as saying: "Expectations were probably so high that they could not have been met when you looked at the European response to the election."
