President Trump attends G-7 meetings in Italy

Trump continues his marathon of meetings with world leaders at the G-7 Summit.

Ahead of his meeting with G-7 leaders Friday morning, Trump met with Japanese Prime Minister Shinzo Abe to discuss North Korea, among other issues.

"It's a big problem, it's a world problem," the president said. "It will be solved at some point. It will be solved, you can bet on that.”

Abe, who joined Trump at Mar-a-Lago in February, joked about playing golf.

“There is one unfortunate thing I have to confess, this time around we will not be able to play golf together,” said Abe.

But in contrast to the collaborative and at times even playful demeanor leaders would assume during the eight years President Barack Obama was in office, Trump's emergence so far on the diplomatic circuit has shown his willingness to use the meetings to confront world leaders and openly express his grievances.

The administration further revealed Friday that it does not plan to lower sanctions on Russia, but could instead look to get tougher on the country.

Gary Cohn, Trump's chief economic adviser, said yesterday that the U.S. doesn't have a position on the subject, leading to speculation that lifting sanctions might be on the table, but has since sought to clarify the White House's position.

“We are not lowering our sanctions on Russia," Cohn told a pool of reporters. "If anything, we would probably look to get tougher on Russia, so the president wants to continue to keep the sanctions in place."

The new administration's position on sanctions against Russia, particularly those imposed in 2014 over Crimea, has been a source of concern among European leaders.

In the evening after the meetings, Trump and the first lady attended a G-7 concert by La Scala Philharmonic Orchestra before the leaders and their spouses sat down for dinner.
