In their first bilateral economic talks ever, Japan and India agreed Monday to strengthen joint efforts to develop India's infrastructure and will try to forge a specific plan by winter, Japanese officials said.

Foreign Minister Koichiro Genba, trade minister Yukio Edano and Financial Services Minister Shozaburo Jimi participated in the economic dialogue in New Delhi with Indian External Affairs Minister S.M. Krishna and Commerce and Industry Minister Anand Sharma.

The agreement follows one made in December by Prime Minister Yoshihiko Noda and Indian Prime Minister Manmohan Singh to jointly invest $9 billion in the Delhi-Mumbai Industrial Corridor, a project aimed at building a freight railway and other infrastructure.
