Ottawa: US President Barak Obama will attend the North American Leaders' Summit to be held in Canada in late June, US Ambassador Bruce Heyman to Canada said here on Wednesday. Obama will travel to Ottawa on June 29 for the North American Leaders' Summit, where he will meet with Prime Minister Justin Trudeau and President Enrique Pena Nieto of Mexico, Xinhua quoted Heyman as saying. The summit is a trilateral annual meeting between Canada's prime minister and the presidents of Mexico and the US. The meeting highlights the importance of continuing to strengthen the bilateral and trilateral ties between the US, Canada and Mexico, the US ambassador said. Trudeau also announced on Wednesday that he will meet with Obama and Pena Nieto in Ottawa on June 29 for the summit. "I look forward to meeting with President Obama and President Pena Nieto to make real progress on the challenges we collectively face -- whether how we can expand trade between our nations, build competitive clean growth economies, or create real help for middle-class families," Trudeau said. Trudeau's announcement and Heyman's statement came almost the same time after months of reported intense, behind-the-scenes negotiations between Canada and its North American partners. The Ottawa summit will be the first to be held in Canada in nearly a decade. The last summit was hosted by President Pena Nieto in 2014 in Toluca, Mexico.
