Indonesia's President-elect Joko "Jokowi" Widodo is calling for more investment from Japan, saying it is "very important for Indonesia" to create jobs, solve energy problems and build infrastructure.

In an interview in Jakarta, Jokowi, who will take office in October, noted that Japan has been "our largest partner" and that bilateral trade totals $46 billion.

He said manufacturing is a key area in which the country hopes to attract foreign investment.
