Tokyo: With the lifting of the sanctions, Japanese insurance companies will be able to issue policies covering trade deals involving Iran. Japanese business will also be able make new investments in Iran’s oil and gas sector.

An investment agreement between Tehran and Tokyo is expected to be signed soon. Japanese companies are already lining up to resume business ties with Iran, with Suzuki Motor Corp on Thursday saying it was considering returning to the Iranian market.

The International Atomic Energy Agency ruled on Saturday, 16 January, that Iran had abided by an agreement last year with six world powers to curtail its nuclear programme, triggering the end of sanctions.

The United States and other countries formally lifted banking, steel, shipping and other sanctions on Iran, a major oil producer that has been virtually shut out of international markets for the past five years.

Iran has always denied its nuclear programme was aimed at obtaining an atomic bomb.

Washington still maintains separate, less comprehensive sanctions on Iran over its missile programme.

That has left some companies cautious, with Japanese oil refiners telling Reuters last week they will keep using special government insurance to ship Iranian oil because of uncertainty over whether US insurers can provide coverage.
