Japan and Iran are expected to sign a bilateral investment treaty next week, sources said Thursday.
Foreign Minister Fumio Kishida and Iranian Economic Affairs and Finance Minister Ali Tayyebnia will sign the pact during a ceremony in Japan, the sources said.
Tayyebnia, expected to visit Japan for three days from Wednesday, is scheduled to deliver a speech at an investment seminar to be hosted by the Japan External Trade Organization on Feb. 5.
The Japanese government lifted its economic sanctions against Iran Jan. 22.
The government aims to win approval from the Diet for the investment pact during its ongoing ordinary session.
