According to a 2005 Senate subcommittee report, Picco provided his services on a number of occasions from 1997 to 2003--overlapping with his Dialogue appointment as a U.N. special representative and undersecretary-general--as a consultant on Oil-for-Food to Bayoil, a company owned by Houston oil man David Chalmers.
For U.N. purposes, the Dialogue of Civilizations faded away in early 2005, only to be replaced that same year by the current Alliance of Civilizations.
Apart from much jetting around and private palaver among eminent people under U.N. auspices, the chief visible product of the Dialogue was a report, released in book form in the fall of 2001.
