The second difference is that while the old regionalism was a one-dimensional structure
(covering only trade and security issues), the new regionalism has a multidimensional
structure (including economics, policy, security, culture, and environment). For this
reason, meanwhile, the European Union (EU) was considered the most important and
effective structure in the old regionalism period, the expansion of the concept of
cooperation in the new regionalism period paved the way for the emergence of new
structures such as the Association of Southeast Asian Nations (ASEAN), the North
American Free Trade Agreement (NAFTA), and the South American Countries Common
Market (MERCOSUR). The last differences are that whereas the old regionalism focuses
on state-centered and regional-level problems, the new regionalism, on the other hand,
focuses not only on regional problems but also on solving global problems and includes
both state and non-state actors in this process (Hettne and Söderbaum, 2006: 181-182).
Especially for developing countries, regional cooperation is used as a tool. These
countries alone lack marketing power in the international system in terms of their
agricultural products or energy resources. In addition, they tend to cooperate more within
the region due to could not hold the power in their hands to resolve both regional and
international problems (Rahman, 2012: 5). The main purpose of regional cooperation is
to solve the problems between the states of the same region in mutual trust and
understanding and to accelerate economic growth, social progress, and cultural
development (Martin and Sohail, 2005: 43). It is aimed to increase the mutual
dependence of state within the region. With increasing interdependence, the state tries
to solve it by communicating before the problems that arise in the region for their interest
turn into conflicts (Khan and Haider, 2004: 1-5).
1.2. Regional Cooperation Methods
Regional cooperation in more than one field emerges due to geographically formed
according to the common needs and problems of each region. The established
cooperation structure generally emerges in areas where it is considered important for the
sovereignty and national interests of the regional states. For this reason, there are many
types of cooperation in many different fields today. In this section, regional economic
cooperation, regional security cooperation, regional environmental cooperation, and
finally regional water cooperation types are mentioned as they are related to the study.
Regional economic cooperation directs some states in the region to increase their
cooperation activities on issues such as mutual trade agreements, trade tariffs,
technology, investment, joint ventures, customs agreements, and monetary policies.
While establishing the economic cooperation mechanism between the states, should be
established in a way that will provide mutual equality and benefit between the member
states (Asian Development Bank, 2013: 4). The regional security cooperation mechanism
aims to reduce the tension and conflicts, and this situation helps to eliminate the problem
of miscommunication between member states and at the same time helps to easily
establish common interests and goals (Hettne and Söderbaum, 2014: 181). NATO and
ASEAN exemplify this model. The security community, which is the latest model, is a
state community where members of the community will not fight each other physically
