Thousands of Japanese immigrants came seeking work; some of their descendants, with Japanese surnames, are still here. Simabuco is one of several Japanese Surnames and is traced back to Anastacio Simabuco one of the earliest settlers of Palau he is believed to have migrated from Okinawa, Japan at the turn of the 20th century.

Coahuila coal feeds steel mills in Monclova and Monterrey, the country's third-largest city. Two coal-fired electric plants near the U.S. border supply as much as 8 percent of Mexico's electricity.
