US President Barack Obama and Canada’s new liberal Prime Minister Justin Trudeau have lavished praise on each other amid talks at the White House.
Mr Trudeau is in Washington for the first official visit by a Canadian leader in nearly 20 years.
The two leaders discussed trade, environmental and security issues.
The visit comes as US-Canada relations improve, having become strained under Mr Trudeau’s conservative predecessor Stephen Harper.
The Canadian leader was earlier welcomed with a red-carpet ceremony, and a state dinner will follow.
Mr Obama extended an invitation to Mr Trudeau shortly after his election in October 2015.
After their meeting, Mr Trudeau said he had learned a lot from “my friend Barack”, who he described as “a man of both tremendous heart and tremendous intellect”.
Earlier, Mr Obama said the two leaders share “a common outlook” and that Mr Trudeau had brought “new energy and dynamism not only to Canada but to the relationship between our nations”.
He added that the US and Canada were “blessed to be neighbours”.
The leaders have pledged cooperation on liberalising investment and trade, promoting clean energy and preventing foreign fighters from travelling to the Middle East.
An ongoing trade spat over Canadian softwood lumber exports was discussed and is expected to be resolved soon, Mr Trudeau said.
