Presidential hopeful Alberto Fernández arrived in Bolivia this afternoon, the first stop of a two-day mini-tour.
The Frente de Todos hopeful arrived in Santa Cruz de la Sierra for a meeting with Bolivian President Evo Morales, who faces his own re-election seven days before Argentina's election is due to take place.
Fernández, the favourite to win October 27's presidential race after defeating President Mauricio Macri by a huge margin in last month's PASO primaries, was due to take a late dinner with Morales after the duo began talks at 8pm local time.
It will be a brief stay in Bolivia, however, for Fernández, who will fly off tomorrow morning to Lima, arriving around midday.
In Peru, the former Cabinet chief will meet with President Martín Vizcarra, on the second stop of his brief trip overseas.
That evening, he will dine with the the president of the Peruvian Congress and some lawmakers.
Its the second tour Fernández has taken overseas, following his visits to Spain and Portugal earlier this month.
The Frente de Todos hopeful will be accompanied on his trip by Campaign Manager Santiago Cafiero, Communications chief Juan Pablo Biondi, the mayors of San Martín and Hurlingham, Gabriel Katopodis and Juan Zabaleta, and national lawmaker Felipe Solá, among others.
