Since the commencement of the Pacific Agreement on Closer Economic Relations Plus negotiations in 2009, the Pacific Forum Island Countries have maintained that their main gain from this Free Trade Agreement is in labour mobility. Free Trade Agreements, such as the Pacific Agreement on Closer Economic Relations Plus, are considered crucial for enhancing labour mobility gains for Pacific Forum Island Countries, particularly given the constraints associated with multilateral trade agreements and unilateral initiatives.
