US, Canada and Mexico overhaul 25-year-old trade accord

Officials from Canada, Mexico and the United States have signed a fresh overhaul of a quarter-century-old trade pact that aims to improve enforcement of worker rights and hold down prices for biologic drugs by eliminating a patent provision.

The signing ceremony in Mexico City launched what may be the final approval effort for Donald Trump’s three-year quest to revamp the 1994 Nafta, a deal he has blamed for the loss of millions of US manufacturing jobs, Reuters reports.
