The first part of the chapter deals with a journey through China built in Mendoza's text, in all its main meanings, from human and physical geography to ritual life. The second half of the chapter deals with the controversial position of Juan González de Mendoza in the debate on the conquest (military or spiritual) of the Celestial Empire. Some authors have suggested that the Augustinian was in favour of armed intervention in China to introduce the Christian faith, which is not accurate. Although it is true that there was a current of opinion among the Spanish authorities in Manila (and in Mexico, the metropolis of the Philippine colony) asking Philip II to decide to intervene in China, Mendoza was an apologist for a peaceful relationship based on evangelization without weapons. At this point, his work is studied in the service of more strategic interests, for example, in the Roman context of competition between religious orders.
