As for Mr Trump's threat to place high tariffs on European imports, Mr Salvini and Vox president Santiago Abascal downplayed the danger and said EU taxes, such as the Green Deal, and regulations are a bigger risk to Europe's prosperity.
Hungarian Prime Minister Viktor Orban, Italy's deputy premier Matteo Salvini, French National Rally party leader Marine Le Pen and Netherlands' PVV party founder Geert Wilders were among those at the gathering organised by Spanish far-right party, Vox.
Ms Le Pen said the European leaders at the gathering, whose Patriots for Europe group has 84 seats in the European Parliament, "are the only ones that can talk with the new Trump administration".
Germany's election later this month represented a "historic opportunity", Mr Salvini said, as the far-right Alternative for Germany (AfD) party is polling in second place, behind centre-right opposition leader Friedrich Merz's Union bloc.
Referring to what he called "the Trump tornado", Mr Orban said the Republican candidate's victory in November's US presidential election and subsequent return to the White House had "changed the world in just a few weeks... yesterday we were heretics, today we're mainstream".
