Observers attend a negotiation meeting but do not participate in the negotiation itself and do not sign the agreement that formalizes the result of the negotiation.
There are three categories of observers:
1. representatives of international institutions:
2. representatives of permanent members of the Paris Club which have no claims concerned by the debt treatment (for example creditors whose claims are covered by the de minimis provision) or that are not creditors of the debtor country concerned but nevertheless want to attend the negotiation meeting;
3. representatives of non Paris Club countries which have claims on the debtor country concerned but are not in a position to sign the Paris Club agreement as ad hoc participants, provided that permanent members and the debtor country agree on their attendance.
