This article introduces the concept of international clientelism and discusses how this diplomatic tool was employed by Venezuela under Hugo Chávez and Nicolás Maduro as a means to get political support from several Latin American and Caribbean countries. We operationalize the concept and apply it to assess Venezuelan practices put forth in the region. We argue that the reach of Caracas’s diplomatic strategy is broader and deeper than that of simple vote-buying tactics, as it implies the promotion of structural rather than contingent ties, shielding the country against unfavorable moves in international fora. An empirical test using data for all LAC countries for the years 1999–2015 confirms that clientelistic linkages produced political support for Venezuela at the United Nations General Assembly while also moving its partners away from the United States in that institution.
