In the Arab world, on the Indian subcontinent, in Africa and in Latin America, solidarity is lacking and developmental rates are slowed by intra-regional rivalries and misunderstandings. In South America rivalry between Argentina and Brazil is notable, and there is a sense of difference between Andean countries and other OAS members. In Southeast Asia, ASEAN members and non-members cannot unify on a regional basis to further development. In Southern Africa, the region is neglected while civil wars and international hostilities continue. The lack of, or a weak sense of regional identity afflicts the Caribbean, the less developed countries of the Mediterranean basin including insufficiently developed parts of Europe, and it afflicts central Africa.
