French President Emmanuel Macron and Brazilian President Luiz Inácio Lula da Silva will debut a diesel-powered submarine developed in Brazil using French technology at the Itaguai shipyard near Rio de Janeiro.
Paris has delivered its third submarine to Brasilia. It is part of the Prosub programme, which was launched by former French President Nicolas Sarkozy and President Lula in 2008.
President Macron is the first French president to visit Brazil in eleven years. The officials are gathering this week to try to repair relations between the two countries following years of disagreements with former President Jair Bolsonaro.
President Macron and President Lula also announced on Tuesday a commitment to invest one billion euros in Amazon. In a joint statement, they stated that the funds will be distributed over the following four years to safeguard the rainforest.
It will be a collaboration between state-owned Brazilian banks and France's investment agency. Brazil and France both stated that private resources will be welcomed.
President Macron began his three-day tour to Brazil in the Amazon city of Belem, where he met with his Brazilian counterpart. The French president then boarded a boat to the Combu island to meet with Indigenous leaders.
Both President Macron and President Lula joined a Greenpeace Brazil rally with placards reading "No oil in the Amazon." The Brazilian government has considered permitting oil drilling in a location near Belem, in the state of Para.
During his speech, President Lula stated that President Macron's visit is part of a worldwide effort to reinforce rainforest safeguards.
