This paper will focus on the knowledge produced by Manuel de Agote y Bonechea (1755-1803), first factor of the Royal Philippine Company (Real Compañía de Filipinas) in Canton by the end of the 18th century, as reflected in the collection of diaries that he wrote in China between 1787-1796. As a representative of a chartered company, Agote commited to his mercantile duties as well as devoted to a representative role, while gathering intelligence and informing his superiors. His diaries thus collect a great amount of miscellaneous information, combining mere commercial data with deep assessments of the Canton trade, as well as providing information on the Spanish side of it, together with specific informations about China at the end of the Qianlong era and the Philippines during the Bourbon reforms. The diaries do not make up a strictly coherent essay but rather compile scattered information through the years, and yet, these show a coherent discourse, serving an imperial agenda, as an effort to generate knowledge and make it known both to public servants and to the general public. Thus, Agote not only witnesses the actitivities of the Royal Philippine Company in China and Asia, poorly known by the historian, but also showcases the position of Spanish public servants of his generation that, as cracks were evident in the building of the Spanish Empire during the second half of the 18th century, were ready to take action through the spread of knowledge.
