According to AFP, Tokyo has been seeking a waiver that would allow it to continue importing Iranian oil, however, it appears unlikely to win one. "We've been saying we will observe a government decision [on Iranian oil imports], but we can't comment further as we don't disclose information on individual trades," a spokeswoman for wholesaler Showa Shell Sekiyu told AFP on Monday.
