Japan urged Iran on Thursday to implement all the resolutions adopted by a U.N. nuclear watchdog as a way to help it gain support from other countries, a Japanese official said.

Foreign Minister Yoriko Kawaguchi also told visiting Iranian Deputy Foreign Minister Mohsen Aminzadeh that Tehran should be transparent in its fulfillment of the International Atomic Energy Agency resolutions, the official said.

The most recent resolution, adopted by the IAEA board of governors last month, states that Iran's cooperation with the international organization has not been as full, timely or proactive as it should have been.

"We intend to sincerely cooperate with the IAEA," Aminzadeh was quoted as replying to Kawaguchi. "We will make efforts to resolve the issue in a transparent manner."
