In both communications, Tusk called on European Union leaders to recognize the serious threat posed by an "assertive China", "Russia's aggressive policy" and "radical Islam" such as the Islamic state group also known as ISIS, adding that these issues "as well as worrying declarations by the new American administration, all make our future highly unpredictable".
According to Tusk, the new United States administration seems to have "put into question the last 70 years of American foreign policy". The decision to leave was the biggest setback for the European Union in decades, and Trump didn't endear himself with many European Union leaders by saying that Brexit "will be a tremendous asset and not a tremendous liability".
"We should use the change in the trade strategy of the United States to the EU's advantage by intensifying our talks with interested partners, while defending our interests at the same time", the Polish politician commented. Meanwhile, Steve Bannon, the president's chief strategist, has made no secret of his sympathies for anti-EU parties in Europe, including French far-right presidential candidate Marine Le Pen.
The EU is at odds with the Trump administration over an executive order banning entry to the United States of citizens from seven Muslim-majority countries. "Armenpress" reports in a letter addressed to national leaders Tusk said that the current threats facing the European Union are most risky since the Rome Treaty.
But he warned that European-American ties were still essential for the future.
Tusk wrote to the leaders that "in politics, the argument of dignity must not be overused", before adding that "today we must stand up very clearly for our dignity, the dignity of a united Europe - regardless of whether we are talking to Russia, China, the USA or Turkey".
The president of the European Council also said the EU should use the change in the trade strategy of the U.S. to the EU's advantage by intensifying talks with interested partners.
On Thursday, the eurozone's top official Jeroen Dijsselbloem voiced concern over Trump's policies and urged the European Union members to use the potential loss of American partnership as an opportunity to strengthen the bloc's single currency. We can not surrender to those who want to weaken or invalidate the Transatlantic bond, without which global order and peace can not survive.
At the Malta summit, the 27 will be focussed primarily on migration in the Central Mediterranean, and in particular from and around Libya.
