The president’s combative style and unilateral actions were not welcomed by European officials, who were used to coordinating some policies with the United States. However, the EU is hoping that a Biden administration will mean more cooperation going forward.”It is more than a transition, it is an opportunity to rejuvenate the transatlantic relationship,” Charles Michel, European Council president, said on Wednesday.The European Union announced in December a plan on how to improve the transatlantic relationship. This is focused on four major policy areas: health response, climate change, trade and tech, and security.But European officials are also aware that when it comes to digital taxation, for instance, it might be hard to reach an agreement overnight.President- elect Joe Biden.The Washington Post | The Washington Post | Getty Images”We have our differences and they will not magically disappear,” Michel also said at the European Parliament.Earlier this week, European finance ministers discussed with the former economic advisor to the Obama administration, Larry Summers, the future of the transatlantic relationship.According to one EU official, who did not want to be named due to the sensitivity of the talks, Summers said this will be the first time since the fall of the Berlin Wall that there will be such a close relationship between the U.S. and the EU.However, Summers also tried to manage expectations, suggesting that it may take a bit longer than expected for the new administration to settle in and appoint all the necessary officials it needs.
