Humberto Calderón Berti


Humberto Calderón Berti is a Venezuelan geologist, petroleum engineer, diplomat, politician and author, named in 2019 as ambassador to Colombia by interim Venezuelan president Juan Guaido during the 2019 Venezuelan presidential crisis, and welcomed by Carlos Holmes Trujillo, Colombia's foreign minister.
Calderón Berti is a former president of PDVSA, and the country's former Minister of Energy and Mines, as well as former Minister of Foreign Affairs. He is also a former OPEC president. His undergraduate degree was from the Central University of Venezuela, and he has a Master's in petroleum engineering from the University of Tulsa in Tulsa, Oklahoma.
In 2003, he and other former PDVSA petroleum executives founded the Colombian company, Vetra Energia, S.L. He solicited and was granted Spanish citizenship, where he has family and cultural ties, in 2018 because of persecution due to his membership in Venezuela's Social Christian political party.
On 26 November, Guaidó dismissed Calderón as ambassador in Colombia, citing plans to change foreign policy. Venezuelan diplomat Diego Arria condemned the dismissal, calling it a "huge mistake".
