What It Means in Practice
Track II diplomacy describes unofficial dialogue between non-state actors — academics, retired officials, religious leaders, business figures, NGO staff, journalists — on issues that official government-to-government (Track I) channels cannot or will not engage. The term was coined in 1981 by US diplomat Joseph Montville to describe that runs in parallel with official diplomacy. Track II participants speak for themselves, not their governments, which lets them explore ideas without committing anyone to anything.
A Track II convening typically gathers a small group — twelve to thirty people — for several days in a neutral country, under Chatham House Rule (no attribution). Sessions are facilitated by professional mediators or research institutes. Outputs are usually informal: a chairman's summary, an unattributed concept note, or simply the relationships that form.
Why It Matters
Official diplomacy is constrained by what governments are prepared to say in public. When two governments have no diplomatic relations, or when domestic politics make any concession explosive, Track II provides a channel that exists precisely because it is deniable. The Oslo Accords are the most famous example — what became the breakthrough Israeli-Palestinian agreement began as Track II discussions between Israeli academics and PLO officials, organized in 1992 by Norwegian researchers Terje Rød-Larsen and Mona Juul, with no official US or Israeli government involvement.
Track II is also where new ideas get incubated. Arms control breakthroughs — nuclear test bans, biological weapons restrictions, — frequently appeared first in Track II venues years before any government would touch them officially.
Track 1.5 and Multi-Track Diplomacy
Practitioners now distinguish several variants. Track 1.5 describes hybrid formats where current officials participate in unofficial venues, getting deniability while still moving the diplomatic needle. The Iran nuclear talks ran a Track 1.5 process at the Pugwash Conferences before transitioning to formal Track I negotiations. Track III refers to civil-society-to-civil-society dialogue that may have no diplomatic component at all — interfaith reconciliation, sister-city programs, joint scientific projects. The full taxonomy ('multi-track diplomacy') was developed by John McDonald and Louise Diamond in the 1990s.
Why Governments Use It
Track II solves three problems for official diplomacy. Deniability: a government can test a position without owning it. Access: Track II convenings can include parties (rebel groups, sanctioned officials, dissidents) that official protocol forbids. Time: Track II builds the relationships and shared analysis that allow a Track I negotiation to move fast once political conditions allow.
Common Misconceptions
New students of diplomacy sometimes assume Track II is the same as 'citizen diplomacy' or general . It is not — Track II is purposeful, structured, and usually connected to specific policy objectives. A backchannel conversation between a former US ambassador and a current Iranian deputy foreign minister is Track II. A peace march is not.
Another misconception is that Track II is always secret. Many Track II processes are public — Pugwash, the Munich Security Conference's Track II offshoots, the Trilateral Commission — though specific session content remains confidential.
Real-World Examples
The Pugwash Conferences (founded 1957) brought US and Soviet scientists together during the Cold War; their Track II work informed the Partial Test Ban Treaty and the Biological Weapons Convention. The Oslo Accords (1993) emerged from a Norwegian-facilitated Track II process. The Geneva (2003) sketched a detailed Israeli-Palestinian permanent-status agreement entirely through Track II. The Six-Party Talks on North Korea ran a parallel Track II process at the Northeast Asia Cooperation Dialogue for years. The Sant'Egidio Community's mediation of the Mozambique peace agreement (1992) is one of the cleanest examples of Track II achieving what governments could not.

The Pugwash Conferences brought together US and Soviet scientists during the Cold War — a foundational Track II channel that informed arms-control breakthroughs.
