While U.S. total net crude oil imports fell during 2013, the share of imports last year from the United States' top three foreign oil suppliers—Canada, Saudi Arabia, and Mexico—was the highest in at least four decades, according to preliminary annual trade data from EIA's Petroleum Supply Monthly report. These three countries provided almost three out of every five barrels of oil imported into the U.S. market last year.
