This brief dossier focuses on the exchanges, interactions and synergies that have developed over the last five centuries between the American and Asian coasts of the Pacific Ocean from a long-term perspective. The aim is to reflect on the close links and strong ties that have been established between America and other continents over such a colossal mass of water from the 16th century to the present day, with the help of the methods and techniques of two disciplines that establish a fruitful dialogue, namely History and Ethnology. In addition, this current edition of our journal includes two articles on a free topic and two reviews.
