There is definitely a time stamp on this PM activity.  With the politics going on south of the border, the PM is putting all his efforts to get an  FTA with China.  The political matrix has the Americans:  tied up in the ME with a questionable play further confused with the new president-elect, The same can be stated regarding Russia, A European union that is losing one of its base economic stabilizers in the next 2 to 10 years, the TPP now a going nowhere FTA with the president elect and  whose debt is owned by the country they blame their woes.   That is instability in spades.  With Trump (a  stage actor) and the Republicans (power above all else), where does an American business man to go?  North!!  ..to Canada where there is stability and access to the world.   Canada, where a banking system is stable,  resource loaded and with a PM willing to talk and access to "Chaina".   And Dawson..  this is what happened behind the scenes, your questions won't change that..
