Warsaw Humanitarian Expo (WHE) is a response to the far too low sales of Polish goods and services serving international organizations. WHE is the only and largest fair devoted to global humanitarian aid in Europe. In the exhibition pavilions of the Ptak Warsaw Expo you will find all entities operating under the United Nations system and NGOs profiled for humanitarian and development assistance. Those who deal with purchases in organizations will come to the fair because they want to know what companies make offers to them, what technological benefits they offer, and how much trust you can have.
