After the election of Jair Bolsonaro as President of Brazil in October 2018, the newly promoted Ambassador Araújo was chosen to be the Foreign Minister in the new Administration.

[8] An anonymous group of Brazilian diplomats published a manifesto lamenting his appointment and claiming Araújo is "manifestly unprepared" and holds "ridiculous" and "absurd" opinions.

[11] During the PT administrations, Araújo publicly supported the core elements of Lula da Silva's and Dilma Rousseff's foreign policy.

[17] On his blog, Araújo has also claimed that climate change is a "cultural Marxism" plot to undermine Western countries in order to support China's growth, and has also lamented the "criminalisation" of red meat, oil and heterosexual sex.

[18] He has called for Brazil to build a new alliance with the United States, Russia, Serbia, India, Italy, Japan and the Visegrád Group nations.

During his tenure, Henrique Fonseca de Araújo acted to prevent Gustav Franz Wagner, a Nazi official and deputy commander of the Sobibór extermination camp, from being extradited to Germany.
