Abstract

Great powers often use high-level visits to reassure weaker states. The literature on public diplomacy shows that these visits can bring a number of advantages while overlooking their potential impact on increasing support for the great power’s security agenda and confidence in the host country’s defense policy and military. This note employed a quasi-experiment in Taiwan, in which three high-profile US Senators visited Taiwan unexpectedly during a one-week national survey (n = 1,500) in June 2021. Propensity score matching and regression discontinuity analysis showed that the visit significantly increased Taiwanese respondents’ confidence in their own military, the government’s security policy, and support for the security policy favored by the US (strengthening the Taiwanese military). Limitations, scope conditions, and suggestions for future work were also discussed.Las grandes potencias suelen utilizar las visitas de alto nivel para tranquilizar a los Estados más débiles. La literatura sobre diplomacia pública muestra que estas visitas pueden aportar una serie de ventajas, al tiempo que pasa por alto su impacto potencial en el aumento del apoyo a la agenda de seguridad de la gran potencia y de la confianza en la política de defensa y el ejército del país anfitrión. Esta nota empleó un cuasi-experimento en Taiwán, en el que tres senadores estadounidenses de alto perfil visitaron Taiwán inesperadamente durante una encuesta nacional de una semana (n = 1500) en junio de 2021. El pareamiento por puntaje de propensión y el análisis de regresión discontinua mostraron que la visita aumentó significativamente la confianza de los encuestados taiwaneses en su propio ejército, la política de seguridad del gobierno y el apoyo a la política de seguridad propugnada por Estados Unidos (fortalecimiento del ejército taiwanés). También se debatieron las limitaciones, las condiciones del ámbito de aplicación y las sugerencias para futuros trabajos.Généralement, les grandes puissances emploient les visites officielles pour réassurer les États plus faibles. La littérature sur la diplomatie politique montre que ces visites peuvent apporter quantité d’avantages, mais omet l’effet potentiel de renforcement du soutien au programme de sécurité de la grande puissance et de la confiance dans la politique de défense et l’armée du pays hôte. Cette note s’appuie sur une quasi-expérience à Taïwan, au cours de laquelle trois importants sénateurs américains ont effectué une visite inattendue à Taïwan, lors d’un sondage national d’une semaine (n = 1 500) en juin 2021. L’appariement sur le score de propension et l’analyse de la régression sur discontinuité ont montré que la visite a fortement renforcé la confiance des Taïwanais interrogés en leur propre armée, la politique de sécurité du gouvernement et le soutien à la politique de sécurité que préféraient les États-Unis (renforcement de l’armée taïwanaise). Nous nous sommes également intéressés aux limites, aux conditions du champ d’application et aux suggestions de travaux ultérieurs.
