OTTAWA, March 17 (Reuters) - U.S. President Donald Trump must stop making “disrespectful” comments about Canada before the two countries can start serious talks about future ties, Prime Minister Mark Carney said on Monday.

"We've called out those comments. They're disrespectful, they're not helpful, and they ... will have to stop before we sit down and have a conversation about our broader partnership with the United States," Carney told reporters in London.
