Fox and Bush, pictured in 2006, appeared to enjoy a warm relationship.
WASHINGTON (CNN) - The two leaders shared a border for six years, but former Mexico President Vicente Fox gives a tough assessment on President Bush in a new book out next month, according to U.S. News and World Report.
In "Revolution of Hope," set to hit book stores October 4, Fox calls Bush "the cockiest guy I have ever met in my life," and is sharply critical of the president's Iraq policy and his immigration stance, according to the magazine.
Though he describes warm relations with Bush, Fox in the book also calls the president's Spanish skills "grade-school" level and says, "I can't honestly say that I had ever seen George W. Bush getting to the White House."
In addition to Bush, Fox also sounds off on his "close but rocky relationships" with former British Prime Minister Tony Blair, Cuban leader Fidel Castro, Russian President Vladimir Putin and Venezuela President Hugo Chávez, according to the books Publisher, Penguin.
Fox served as Mexico's president from 2000-2006.
The autobiography is co-written by Robert Allyn, a Texas-based political consultant who has advised both Fox and Bush.
