Many businesses, large and small, are concerned about the effects that many of the Trump administration proposals or planned proposals would have on trade. Those at issue would reduce Canada and Mexico’s access to the U.S. government procurement market, create a new domestic content provision for autos and tighten regional content requirements, and automatically terminate the agreement after five years unless all three countries agree to renew the pact — known as a sunset clause.

“We see these proposals as highly dangerous, and even one of them would be sufficient to move the business and agriculture community to oppose an agreement that included them,” (Chamber Senior VP John) Murphy said.

The veteran business official said the administration’s proposals for revamping the dispute settlement provisions of the pact have also caused concern, as has another proposal to create a new anti-dumping mechanism for seasonal and perishable products.
