TOKYO – Iran is sharing nuclear technology with North Korea, Israeli Prime Minister Benjamin Netanyahu said in an interview published Wednesday, as Tehran and world powers hold talks aimed at ending a decade-old standoff.

Netanyahu, who is in Japan this week for talks with Prime Minister Shinzo Abe, Foreign Minister Fumio Kishida and other officials, said Iran “would share whatever technology it acquired with North Korea,” the Mainichi Shimbun reported in a front-page piece.

Asked if Pyongyang is receiving technologies linked to nuclear and missile development from Iran, Netanyahu said: “Yes, that’s exactly the case.”

In a separate interview with Japanese broadcaster NHK aired Tuesday, Netanyahu said Iran would use a nuclear deal with world powers as a diversionary tactic to shift world attention before attacking Israel.

“They say that they would reduce production of uranium, but they increase production of centrifuges. It is as if they are acquiring express trains for development of nuclear weapons,” he said, according to an English translation of a Japanese voice-over of his comments provided by the Prime Minister’s Office.

North Korea’s nuclear and ballistic missile program is one of Japan’s major security concerns.

Despite international isolation and extensive sanctions, North Korea appears to be readying to carry out a fourth nuclear test, observers have said, and regularly makes noises about the weaponization of its technology.

While being at the leading edge of Pyongyang’s isolation, resource-poor Japan has maintained friendly relations with oil-rich Iran through its years of ostracism, keeping up a diplomatic dialogue that many developed countries cut off decades ago.

Late Tuesday, during a meeting with Kishida, Netanyahu called both Iran and North Korea “rogue” states.

“We see a danger and a challenge posed by a rogue state arming itself with nuclear weapons. In your case it’s North Korea,” he said.

“We are faced with such a rogue state in the form of Iran and its quest to develop nuclear weapons,” he said.

“Iran continues to deceive the world and advance its nuclear program,” he said, adding “Clearly the Ayatollahs cannot be trusted.”

“And if the international community wants to avoid the specter of nuclear terrorism, they must assure that Iran… not have the capability to develop nuclear weapons,” he said.

Kishida however “stressed…the importance of support by the international community including Israel to the framework of talks” between Iran and five UN nuclear powers plus Germany, the foreign ministry said in a statement.

Abe also made a similar comment on Monday.

Tehran insists its nuclear program is intended only for civilian purposes.

Iran and the five permanent members of the UN Security Council plus Germany are meeting in Vienna for a latest round of talks aimed at drafting the text of a comprehensive and potentially historic deal.

An accord would see Tehran’s atomic program drastically reduced, and sanctions lifted on its lifeblood oil exports in return.
