Most commentary about the nuclear deal with Iran focuses on the implications for the region and U.S. allies in the Middle East and Europe. But it also removes a thorn in the side of the U.S.-Japan relationship. Tokyo’s role as a major importer of Iranian oil meant its cooperation was a key piece of the sanctions campaign against Tehran. Yet that cooperation did not come easy: it required repeated U.S. pressure and was a consistent cold spot in an otherwise warm U.S.-Japan relationship.
Japan and Iran will start negotiations on an investment accord once sanctions are lifted following last month's landmark international deal on Tehran's nuclear program, the Nikkei reported on Wednesday, citing Japanese government sources.
