Public Citizen, the left-of-center public interest group, on Wednesday praised sections of President Trump’s U.S.-Mexico Canada Agreement on trade, saying certain areas represented a significant improvement over the North American Free Trade Agreement.

While the group said not every detail of the agreement was good, some represented steps backwards and much rested on its implementation, it said the deal nevertheless included “important progress” in the area of investor-state dispute settlements and could address some economic issues with the old NAFTA.
