Because this document was made public at the time the agreement was reached, whereas other bilateral agreements have not been, there has been greater opportunity to assess its impact, and some of the material referenced below is based on this bilateral agreement. More recently, an official summary by the WTO of the entire agreement has been released, and the first outside assessments of the entire agreement are now becoming available (WTO, 2001).
