(BBC) Iran's leader Mahmoud Ahmadinejad has promised $1bn (Ј493m) to help Bolivia exploit oil and gas reserves.
Mr Ahmadinejad made the pledge to his Bolivian counterpart, Evo Morales, during a brief visit there - part of a mini-tour to Latin American nations.
Mr Morales said their two countries would "work together from this day on".
Mr Ahmadinejad later flew to Venezuela to meet President Hugo Chavez, his main ally in Latin America. He will also visit Ecuador and Nicaragua.
The tour follows his address to the UN General Assembly in New York.
