Ruiz is president of Condumex Automotive, Mexico's second-largest auto supplier. Mexican suppliers have lost much of their protection from outside competitors under the North American Free Trade Agreement.
He will discuss the changing Mexican auto industry and its integration with the United States and Canada on Jan. 10, when he addresses an afternoon session of the Automotive News World Congress.
Over the past three decades, Ruiz has been at the forefront of the Mexican supply industry.
He was a member of committees that negotiated NAFTA as well as Mexico's auto decrees of 1972, 1977, 1983 and 1989.
At Condumex, Ruiz oversees 17 plants and 5,000 employees who make wire harnesses, cables, cylinder liners, piston rings, shock absorbers and radiators.
Condumex Automotive is a division of the Condumex Group, which is part of Grupo Carso.
