The ___ Club is an informal group of official creditors (primarily wealthy, developed nations) whose role is to find coordinated and sustainable solutions to the payment difficulties experienced by debtor countries.

Answer: Paris

The Paris Club deals with the restructuring of bilateral sovereign debt owed by developing or distressed nations to other governments. In contrast, the 'London Club' handles debt owed to private commercial banks. When a country faces a sovereign default, it typically negotiates with the Paris Club to secure debt relief, rescheduling, or forgiveness.
