This chapter discusses the difficulties, limits, and frontiers to international collaboration in emerging countries. The management of networks and research groups, and dealing with international collaborators are the functions that require new leadership skills. There seem to exist an international division of research labor, hard frontiers, tensions and limits marked for language expressions, publications of results, scarce resources to maintain international circulation, and hard access to the core journal in each area of knowledge. In addressing these issues, we do not intend to present an all-around theorization on the functioning of the knowledge disciplinary fields of research but to combine the critical considerations from contemporary educational theory with research-based evidence to elicit the discussion of alternatives for the improvement of strong research networks.
