The use of EIES varies quite widely across member economies. Based upon an evaluation conducted at the workshop, two economies (KOR; SIN) were determined to maintain high-level operational systems that are well established and highly regarded. Several other APEC economies (BRU; CHN; INA; JPN; MAS; PHI; THA; VIE) are currently developing these systems. Two economies (AUS; PNG) neither have nor are developing EIES at this time.
