In this study, I analyse an exceptional case of international political communication, in which the President of one nation writes directly to the people of another, outside the normal diplomatic channels. I study two missives addressed by Cuban President Fidel Castro to the Mexican people during a situation of conflict between their two countries. They take the form of letters published through the Mexican press. After analysing the context in which Castro’s letters appear, I examine the main discursive characteristics of the texts. The analysis includes speech acts, modality and the persons mentioned in the text. My findings reveal the political intent of these messages: to influence the Mexican political agenda, repositioning Cuba both with respect to the Mexican authorities and leftist politics in Latin America.

常规渠道之外的国际政治：总统写信给他自己以外的人

在这项研究中，我分析了一个国际政治交流的特例，其中一个国家的总统在正常外交渠道之外直接给另一个国家的人民写信。我研究了古巴总统菲德尔·卡斯特罗 (Fidel Castro) 在两国发生冲突期间给墨西哥人民的两封信。它们采用通过墨西哥媒体发表的信件形式。在分析了卡斯特罗信件出现的背景之后，我检查了文本的主要话语特征。分析包括言语行为、情态和文本中提到的人。我的发现揭示了这些信息的政治意图：影响墨西哥的政治议程，在墨西哥当局和拉丁美洲的左翼政治方面重新定位古巴。
