Trudeau brushed aside concerns that NATO's agreement to increase intelligence-sharing in the fight against terrorism comes amid accusations that President Donald Trump and others in the USA are playing fast and loose with sensitive secrets.
"Members of the alliance must finally contribute their fair share and meet their financial obligations", Trump said.
Donald Trump's first trip overseas as president has already taken him to Saudi Arabia, Israel, the West Bank of the Palestinian territories, the Vatican before arriving in Brussels.
Visiting a city he once called a "hellhole" to meet with the leaders of an alliance he threatened to abandon, President Donald Trump will be in the heart of Europe on Thursday to address a continent still reeling from his election and anxious about his support. During his campaign, Trump said he would cancel the climate agreement and stop all US payments to United Nations global warming programs.
What the Sicily stay will likely not offer: a news conference, as Trump appears set to defy presidential tradition and not hold one during the entire trip.
"This call for driving out terrorism is a message I took to a historic gathering of Arab and Muslim leaders across the region, hosted by Saudi Arabia", he said, adding: "The leaders of the Middle East have agreed at this unprecedented meeting to stop funding the radical ideology that leads to this awful terrorism all over the globe".
Asked if he was disappointed that Trump didn't explictly express support for Article 5, he said just by dedicating the 9/11 and Article 5 display he was doing that.
After meeting with Trump on Thursday at the EU, European Council president Donald Tusk said he and the USA president agreed on the need to combat terrorism but some differences loomed large.
The summit marks Trump's final stop on a maiden global trip that began in Saudi Arabia and Israel, where the president was warmly embraced by the countries' leaders. If all North Atlantic Treaty Organisation members had spent just 2 percent of their GDP on defense previous year, we would have had another $119 billion for our collective defense and for the financing of additional North Atlantic Treaty Organisation reserves.
The EU council president said a discussion with Trump produced sharply different views on Russian Federation. Stoltenberg, when announcing NATO's inclusion into the military coalition against IS, said that the alliance will be limited to provide a better platform for coordination and intelligence exchange, which 'does not assume that we will participate in combat operations'. "It will be solved, you can bet on that", Trump said.
The European Union and the United States have agreed to seek to increase trade cooperation, EU executive chief Jean-Claude Juncker said on Thursday, as a major free trade deal now looks a distant prospect.
But Trump increased the pressure, calling that agreement made at a summit in Wales in 2014 "the bare minimum".
NATO Secretary General Jens Stoltenberg also said Thursday morning that the alliance was ready to join the USA -led coalition against the Islamic State, although he said NATO would not have a combat role on the ground in Iraq and Syria. Recalling her personal experiences of growing up in East Germany, Merkel said: "It is not isolation and the building of walls that make us successful, but open societies that share the same values".
Tusk said he told the billionaire U.S. president that they should consolidate "the whole free world around those values, and not just interests".
This came after NATO leaders wrapped up a meeting at the new NATO Headquarters on Thursday.
