That website is not as "fair" you one would think, here's another article on it's homepage. I wouldn't trust it at all. Especially over individuals in the US State Dept. who were sitting in at the negotiations:
In Death as in Life, Chávez Target of Media Scorn
Venezuela's left-wing populist president Hugo Chávez died on Tuesday, March 5, after a two-year battle with cancer. If world leaders were judged by the sheer volume of corporate media vitriol and misinformation about their policies, Chávez would be in a class of his own.
Shortly after Chávez won his first election in 1998, the U.S. government deemed him a threat to U.S. interests--an image U.S. media eagerly played up. When a coup engineered by Venezuelan business and media elites removed Chávez from power, many leading U.S outlets praised the move (Extra!, 6/02). The New York Times (4/13/02), calling it a "resignation," declared that "Venezuelan democracy is no longer threatened by a would-be dictator." The Chicago Tribune (4/14/02) cheered the removal of a leader who had been "praising Osama bin Laden"--an absurdly false charge.
In reporting Chávez's death, little had changed. "Venezuela Bully Chávez Is Dead," read the New York Post's front page (3/6/13); "Death of a Demogogue" was on Time's home page (3/6/13). CNN host Anderson Cooper (3/5/13) declared it was "the death of a world leader who made America see red, as in Fidel Castro red, Venezuela's socialist president, Hugo Chávez."
"The words 'Venezuelan strongman' so often preceded his name, and for good reason," declared NBC Nightly News host Brian Williams (3/5/13); on ABC World News (3/5/13), viewers were told that "many Americans viewed him as a dictator." That would be especially true if those Americans consumed corporate media.
