A Mean food imports from outside the region to all PICTs and to PICTs that were early adopters of PICTA. Only commodities produced outside the region were included; B Mean intra-regional trade between all PICTs and between PICTs that were early adopters of PICTA. Only commodities that were produced within the region were included. For both graphs, each HS6 commodity type was given equal weighting to avoid bulk commodities dominating trends (see methods for calculation). Error bars show 95% confidence interval around the average trade quantity. See Supplementary Table 1 for inclusion and exclusions
