Canadian Prime Minister Justin Trudeau said Wednesday that he will meet US President Donald Trump in Washington Thursday to mainly discuss trade issues.

Trudeau sees the meeting as an opportunity to discuss trade issues with Trump, including US trade frictions with China and the ratification of the North American Free Trade Agreement (NAFTA), before the G20 summit in Osaka, Japan, on June 28-29.

"We're obviously going to have a big G20 coming up and it's an opportunity for us to sit down and talk about China, talk about trade, talk about all the issues that are going to be discussed -- the global issues that will be discussed at the G20 next week," Trudeau said Wednesday before a meeting with his Liberal officials.

He said trade will be a big part of the meeting with Trump as both countries look to ratify a new Canada-United States-Mexico trade deal which is stalled in US Congress now.

"There will be a big conversation about the path of ratification of the new NAFTA, and we're going to make sure that we're keeping in step with them," Trudeau said.

After meeting Trump, Trudeau will meet US Senate Majority Leader Mitch McConnell and House of Representatives Speaker Nancy Pelosi.
