This 4 December 2019 video from the USA says about itself:
As the Vermont senator battles Elizabeth Warren for the left wing of the Democratic Party, he’s increasingly tried to find an edge on foreign policy. Sanders has portrayed his candidacy as one part of a worldwide worker-led movement, praised … leftist leaders across the globe, and tried to articulate a foreign policy further afield of the establishment than Warren’s.
Sanders’ foreign policy views are a clear mark of distinction from Warren in a race in which their domestic agendas are viewed as very similar.
Left-wing leaders around the world see an ally in Sanders — Brazil’s Luiz Inácio Lula da Silva recently thanked him for his “solidarity” and Bolivia‘s ousted Evo Morales called him “hermano Bernie Sanders” — but have not publicly embraced Warren in the same way.
