Our research focuses on the analysis of the speech made by the President of the Democratic Republic of Congo, Joseph Kabila, on the occasion of the inauguration of the Matebe hydroelectric dam in the province of North Kivu in December 2015. The aim is to study the content of the messages in his speech at the inauguration of this power station. We took a semio-pragmatic approach to this subject. The inauguration of the hydroelectric power station was organised by the governorate of North Kivu province, headed by the governor of the province, Julien Paluku Kahongya. The event was preceded by a number of events, including speeches by the partners and reactions from the public, in particular the Head of State and the American partners. These events included, for example, the performance of Congolese music and dances on the themes of peace, war, poverty and so on. In this study, we have accurately interpreted the content of the message or speech by the President of the Democratic Republic of Congo, and given meaning to the content of the message, both spoken and unspoken.
