U.S., Canadian, and Mexican government officials charged with renegotiating the North American Free Trade Agreement (NAFTA) expressed disappointment in the outcome of the fourth round of the talks completed on Tuesday, but vowed to stay at the table.

President Donald Trump spoke to a group of truck drivers and carriers on Wednesday in Middletown, Pa. about the benefits of his tax reform plan, which is backed by strong support from trade group the American Trucking Associations (ATA).

As trade negotiators for the United States, Canada and Mexico are meeting this week to begin the fourth round of the North American Free Trade Agreement (NAFTA) renegotiations, industry leaders remain nervous that the trilateral agreement will fold.

U.S. Chamber of Commerce CEO Thomas Donohue told attendees at the U.S.-Mexico CEO Dialogue the "trilateral commercial relationship [of NAFTA] is far too valuable to American businesses, workers, and economic growth for us to retreat or turn inward."

President Trump's January presidential memorandum has produced a report that identifies 20 sets of regulations and permitting issues as being a top priority for reform for domestic manufacturing.
