Indonesia and Brazil have agreed to cooperate on biofuels after talks covering climate change and food.
The two nations on Saturday signed an agreement for Indonesia to send experts to Brazil to study its biofuel developments.
After talks with Brazilian President Luiz Inacio Lula da Silva, President Susilo Bambang Yudhoyono said Indonesia can learn from Brazil's research and development.
Brazil has been mixing ethanol produced from sugar cane mixed with gasoline for decades, as well as running a vast fleet of vehicles on pure ethanol.
Indonesia aims to make the use of a 2.5 percent blend of biodiesel mandatory by September. Indonesia is the biggest producer of palm oil in the world.
