The Globe and Mail reports in its Tuesday edition that some long-running factors complicated trade talks between Canada and the United States. A four-bylined item led by Adrian Morrow says the first was continuing tension between U.S. Trade Representative Jamieson Greer and Commerce Secretary Howard Lutnick. While Mr. Greer pushed repeatedly over the past 10 months for flexibility on steel and aluminum tariffs in order to land trade deals with Canada and Mexico, Mr. Lutnick held firm against giving ground. The steel industry holds a great deal of sway inside the Trump administration. When a steel magnate makes noise, the issue is dealt with promptly, said one U.S. source. Mr. Greer is in charge of negotiating trade deals, but Mr. Lutnick oversees the administration of the tariffs. Mr. Lutnick's interventions in favour of a harsher deal for Canada helped scuttle the agreement. Canadian trade chief Dominic LeBlanc told Canadian industry leaders that negotiators had a deal with Mr. Greer, but it fell apart when he had to get approval for it from others in the administration. Canadian negotiators felt Mr. Greer was a professional who was dealing with them in good faith but others in the administration may not have been.
