BBC Caribbean report reported that Mitchell says it is clear that small economies need to cooperate more at all levels to effectively take on global challenges.

OECS governments are holding a two day retreat in Grenada.

The retreat comes days after the official start of their economic union which commits them to common policies and free movement of citizens and goods across their borders.

Mitchell, Grenada’s opposition leader told BBC Caribbean that while he has some concerns, he is optimistic that the proposed union will succeed.
