Three levels of promotion
Direct promotion (one-to-one):
Communication reaches directly the prospective participants
Ex. foreign enterprises, training and research institutes, trade promotion organizations, etc.
Promotion through relays of communication (one-to-groups):
Ex. Foreign sectoral associations, chambers of commerce and trade promotion organizations
This can operate as multipliers of communication to their members.
Broad audience promotion (one-to-many):
Ex. international sectoral press, commercial ads and articles, or external websites, through participation with a stand promoting the newly planned fair or in other events.
