International negotiations between organizations project a complexity that makes them a challenge to describe, explain and improve. Their many elements and dynamics challenge especially those researchers and practitioners who seek a comprehensive yet essential understanding of these negotiations. Toward that end, this article develops a new analytic perspective that focuses on three key facets of negotiation-parties' Relationships, parties' Behaviors, and influencing Conditions (RBC)-and their basic [GRAPHICS] interaction. The first section defines international business negotiation, targets the subset of complex, interorganizational negotiations, presents as an example the 1985-86 CGE-ITT telecommunications merger, and considers the partial views of the merger talks provided by existing frameworks. Several reasons then enumerated underscore the need for and potential value of an inclusive, generally applicable perspective for complex negotiations. The RBC Framework, coupled with the Basic Model, are presented in detail, with each key facet defined, illustrated, and supported with references from diverse literatures. The Relationship and Behavior facets incorporate multiple levels of analysis (organizational, group and individual). Conditions encompass four types (circumstances, capabilities, cultures and environments). A temporal dimension completes the framework. The last section of the paper proposes empirical and practical applications of this perspective to international business. The former includes question-asking, model-building and testing, and cumulation of knowledge, and the latter, making sense of myriad details and identifying potential points of influence on counterparts. In these ways, the RBC Perspective integrates existing knowledge and will stimulate future work in the field.
