[3] Trifon would travel to the countries of the Eastern Bloc but also to Latin America, living for some time in Mexico.
[4] In 2021, Trifon was diagnosed with cancer and pulmonary fibrosis, which would ultimately lead to his death in the morning of 18 August 2023 in Paris, having lived his last months in his house in the neighborhood of Butte-aux-Cailles.
From 1983 to 1991, Trifon was the director of the anarchist journal Iztok [fr], the staff of which was composed at the time of Eastern European exiles.
[6] As a linguist, Trifon wrote a book focused on Moldova together with the French Romanian historian Matei Cazacu [fr; pl; ro].
[3] In 2005, Trifon published the book Les Aroumains, un peuple qui s'en va ("The Aromanians, a people on the move").
[6] In 2007, an article by Trifon titled Les Aroumains en Roumanie depuis 1990: comment se débarrasser d'une (belle-)mère patrie devenue encombrante ("The Aromanians in Romania since 1990: how to get rid of a (step)mother country that has become cumbersome"), treating the Aromanian minority in Romania, was published in the French journal Revue d'études comparatives Est-Ouest.
Ovidius University associate professor Enache Tușa argued that Trifon made a relevant and comprehensive analysis on the situation of the Aromanians in the Balkan countries in which they live and that this was possible because he wrote his book in France, free from any political or institutional pressure often present in these Balkan countries.
In the book, among other things, Trifon attempted to answer a rhetorical question that the Romanian Aromanian actor, director and politician Ion Caramitru asked himself during a 2011 television broadcasting of where a country called "Aromania" was located.
