1992. The thickness of lines shows the volume of trade
between countries. Colors distinguish regional trading
blocs. Note that most world trade took place within
regional trading blocs, with the United States, Germany,
and Japan at the center of each of the three main blocs.
(Note: The graphic does not include China, which has
become the centre of a fourth trading bloc since the early
90s.)
