TEHRAN (IRNA) -- Foreign Ministry spokesman Hamid-Reza Asefi said here on Wednesday that the latest report by the International Atomic Energy Agency (IAEA) regarding Iran's nuclear energy activities could have been better.

Asefi told reporters that the IAEA report had in several cases proved Iran's claims that its nuclear activities are peaceful, stressing that it had also shown that Iran is extending a transparent cooperation with the agency.

He said Iran's reported activities to enrich plutonium had been at the very preliminary stages, and just for laboratory purposes.

The Foreign Ministry spokesman further stressed that Iran is still debating with members of the IAEA Board of Governors regarding the upcoming meeting of the board to discuss Iran's nuclear program.

He also said that the talks of Hassan Rowhani, the secretary of Iran's Supreme National Security Council (SNSC), with IAEA officials and Russian leaders over the weekend had been positive.

Elsewhere in his remarks, Asefi said Foreign Minister Kamal Kharrazi will visit Japan and China next week to discuss mutual ties as well as peaceful nuclear energy activities.

The IAEA is refusing to provide Iran with the nuclear expertise that under the agency's regulations it is entitled to receive, arguing that Tehran must first sign an additional protocol of the NPT that allows snap inspections of its nuclear sites.
