International participations consist of official state participation of countries, which take part in the Exhibition through their embassies or other state entities, as well as individual foreign companies interested in the Greek market.

The international participation pavilion goes beyond showcasing various state services; it presents a diverse array of products representing each country's production, spanning both modern and traditional items. Additionally, it features tourist and cultural services aimed at fostering cultural exchange and facilitating commercial transactions among the countries, thereby capturing the interest of a wide range of visitors.

Moreover, important chambers of the country participate in the same pavilion with the aim of promoting small and medium enterprises that have modern local products and services, contributing substantially to the development of trade.
