This chapter describes the proliferation of networks, which foster the  development and growth of the countries. Small and informal networks, structured and somewhat more formal scientitifc and technical networks and lastly, formal multinational networks are exlored. In author's veiw the management of networks, that are made up of sovereign nations, is fundamentally different from managing companies, organizations, or ministries that fall under a single authority and are based on cybernetics scenario. Networks by definition must retain the same level of flexibility and ambiguity that characterize the behaviour of its members. Network management, based on IDRC, is discussed in this chapter.
