"When most people think of diplomacy, they think of official contact between government representatives, also known as Track I diplomacy. Track II diplomacy, on the other hand, involves almost entirely unofficial contacts. These unofficial contacts can include dialogues and exchanges between influential non-governmental actors from different countries, designed to build trust and increase communication. In addition, Track II initiatives can be useful when there are blockages at the official level and when a secondary, unofficial venue is needed to explore new or challenging ideas."
