European leaders are hoping to use key meetings with US President George Bush in Brussels on Feb 22 to repair transatlantic relations following two years of bitter acrimony over the Iraq invasion.
European and US officials have been going out of their way in the run-up to the presidential visit to highlight their eagerness to start a new chapter in relations and put past differences behind them. But while the mood is clearly mellower than in recent years, abiding disagreements between the two sides on a range of foreign policy, human rights, trade and environmental issues make it unlikely that the fractures in transatlantic ties can heal overnight.
The EU's plans to lift a 15-year old arms embargo against China as well as European efforts to find a diplomatic solution to end the current nuclear stand off with Iran have emerged as the two strongest points of divergence.
Europeans are also unhappy with America's refusal to sign up to the Kyoto protocol on climate change and Washington's still hesitant role in reshaping the United Nations.
Crucially, while EU policymakers voice a strong desire to forge more forceful ties with Washington, they also insist that the 25-nation bloc will no longer accept a mere walk-on role as junior partner in the transatlantic alliance.
With European public opinion still largely suspicious of the US - huge protests are expected to greet President Bush in Brussels - EU leaders have to be careful about just how close they want to get to Washington. This is especially the case for French President Jacques Chirac and German Chancellor Gerhard Schroeder - the two EU leaders most opposed to the Iraq invasion.
Also, while clearly buoyed by America's new interest in the EU and US Secretary of State Condoleezza Rice's repeated assurances during a recent European tour that Washington wanted to see a "strong and united EU", officials in Brussels have few illusions about America's ambivalence at having to deal with a more confident and self-assured Europe.
The US administration has in fact been sending mixed signals to Europe. In contrast to Condoleezza Rice's gentle courting of the EU, US Defence Secretary Donald Rumsfeld showed his indifference to the emerging global ambitions of the bloc at a recent international security conference in Munich.
Nato, and not the EU, was the most appropriate channel for promoting transatlantic ties, Mr Rumsfeld insisted at the meeting, contradicting Ms Rice's insistence that the alliance was based on two equally important pillars - Nato and the EU.
Washington's change of heart over Europe is clearly prompted by a belated realization it needs European help to deal with post-conflict Iraq. In fact, despite their past rancour over the war, now that Iraq has held elections, this is one area where Europeans and Americans now see - almost - eye to eye.
European governments have said they will undertake a first-ever collective police training mission for Iraq. The programme to train around 800 senior Iraqi judges, police and other officials is, however, expected to take place outside the country due to security concerns.
The EU has also said it wants to play a role in helping Iraq draft a new constitution. Agreement is also expected next week on joint transatlantic efforts to secure elusive Middle East peace.
CHINA EMBARGO: But areas of dissent remain. Ms Rice has cautioned the EU against lifting a 15-year-old arms embargo against China, saying such a move could destabilize the military balance in Asia.
Some EU leaders, however, insist that the ban will be replaced by a more effective code of conduct which will ensure that there is no transfer of sensitive technology to Beijing.
Seeking to defuse transatlantic tensions over the issue, the EU's foreign and security policy chief Javier Solana has called for Washington and Brussels to establish a strategic dialogue on China's emerging power.
European officials are not expecting any major changes in US policy as a result of Mr Bush's visit. But they are hoping the talks will help restore trust between the two sides and convince the US leader of Europe's growing clout on the global stage.
Mr Bush has made clear that he is looking for a fresh start with European allies. America's new pro-EU rhetoric sounds impressive but it's the nuts and bolts of US policy in the coming months that will determine whether transatlantic ties are really back on track.
