Visiting Bangladeshi Prime Minister Sheikh Hasina signed a joint statement with counterpart Shinzo Abe on Monday in Tokyo to seal Japan's pledge to extend up to ¥600 billion in economic assistance to the country over the next four to five years.

The funds, mainly in the form of loans, will be used to build infrastructure and other projects in Bangladesh.

The two countries also agreed to launch a meeting of experts to discuss the lessons Japan has learned so far from the Fukushima nuclear disaster, Abe told reporters after the meeting.
