Geographical proximity influences the formations of regional organisations in the following ways-

• Countries that are geographically close to each other generally have somewhat similar interests and needs. Therefore, their identification becomes easier.

• Collaboration between countries located close to each other provides the region with security and strengthens it.

• The member countries collectively deal with each other and the rest of the world as well in a collective fashion and have synchronised growth and development.

• The countries would generally share some common historical and cultural background owing to their geographical proximity and hence would provide a strong subject to the countries to bond on.
