Infrastructural Linkages in Sri Lanka-India Relations Urmila Phadnis IN a pioneering collaborative effort on 'Linkage Polities', James N Rosenau and others have attempted to define and identify linkages between national- international systems or 'policy-external environment linkages', 'as Rosenau calls them.1 In this process, a broad set of insights and findings regarding the relevance of 'environment' for the establishment and maintenance of linkages, the role of 'linkage elites' and the alternate strategies which they pursue to aggregate their political power are presented. However, most of the papers seem to be more concerned with the 'processes' of linkage politics than with its structures. Also, notwithstanding the underscoring of the 'contiguous'2 or 'regional' environment as a stimulus for such linkages in a couple of papers, such infrastructural linkages are not fully identified. Nor are their interactions exhaustively explained.
