US President Donald Trump on Friday is expected to clash with other world leaders as deep divisions between both parties on climate change and trade are expected to be exposed.
The G7 leaders agreed on Friday to combat the financing of terrorism and to resist the threat of returning foreign militants, according to the joint declaration adopted on the results of the first day of the G7 summit in Italy.
That means the G7 is unlikely also to reprise its oft-used terminology against protectionism, after Trump in Brussels this week reportedly described the Germans as "bad, very bad" in their trade practices.
Sicily is on the front lines in Europe's migration crisis, the first landfall for most of the more than 180,000 migrants who arrived in Italy previous year - and the reason the Italian government chose Sicily as the backdrop for this summit.

Mr Trump has also been threatening that he would pull out of the 2015 Paris Agreement - the world's first ever universal climate change deal signed by 195 nations.
However, there was relief that Trump agreed to language in the final G7 communique that pledged to fight protectionism and commits to a rules-based global trade system.
Italy chose to stage the summit in Sicily to draw attention to Africa, which is 140 miles (225 km) from the island at its closest point across the Mediterranean.
Residents of the hilltop Sicilian town of Taormina are cheering and waving as the leaders of the Group of Seven wealthy democracies pass by - a rarity for global summits, where ordinary people are usually kept far away for security reasons.More news: Bella Thorne and Scott Disick dunzo after poolside PDA fest

The leaders also voiced solidarity with the United Kingdom after Monday's bombing in Manchester in which 22 people, including children, were killed.
One man toted his groceries through the crowd, and two little girls in white T-shirts were waving at the leaders.
That comment also referred to the Nice truck attack last summer that killed children and young families at a fireworks display, as well as the attack on a concert at the Bataclan theater in Paris.
French President Emmanuel Macron praised President Donald Trump's "capacity to listen" and his "intention to progress with us".
"I think we hit a home run no matter where we are", Trump told the soldiers.
As a newly appointed special counsel is beginning his investigation into links between the Trump campaign and Russian officials, Kushner has become a focus of the probe.
He says: "President Trump should join these leaders in protecting Americans from the mounting impacts of climate change and reaping the economic benefits of the clean energy revolution, rather than trying to shore up the flagging fortunes of the polluting coal and oil industries".
