The governmental resolution authorizing the attendance, which was endorsed by Peruvian President Martin Vizcarra, was announced on Saturday by Peru's official news agency Andina.
The attendance of the Peruvian president of the Council of Ministers at the ceremony reflects the importance of Peruvian-Argentinean relations and the deep economic, political and cultural ties between the two countries, according to the announcement.
It contributes to generating spaces for the identification of new areas of cooperation, strengthening traditional friendship ties between the two countries, and reaffirming the shared vision of integration, the announcement added.
Due to a heavily loaded agenda, President Vizcarra will not undertake any trip abroad until after the next legislative elections, which will take place on Jan. 26.
Fernandez's inauguration will have the attendance of Argentinean officials and legislators as well as foreign dignitaries and representatives from around the world.
