Qassemi made the comment in reaction to reports suggesting a visit to Iran by Shinzo Abe had been cancelled.
“There has been no talks and plans on the Japanese premier’s trip to Iran after all; so, talk of its cancellation is pointless,” he said in a Tuesday statement.
“The news circulated by some Japanese news agencies is untrue and sheer lies,” he said.
The spokesman described age-old Tehran-Tokyo as very good.
“We welcome the promotion of ties at all levels with Japan as an old friend and partner, but no trip to Iran has been on the agenda in the foreseeable future,” he noted.
