The Russia-Iran talks held in Moscow March 7-9 on Tehran's outstanding debt for the construction of the Bushehr NPP in the south of the Islamic Republic produced no positive results.
"Representatives of Russia and Iran will today continue talks on problematic issues related to the Bushehr NPP. The Russian delegation will include experts that have arrived from Moscow, and also specialists from the company's Iranian office," Atomstroyexport said.
Russian specialists are completing the construction of Iran's first NPP under a $1 billion contract signed in 1995, but Russia claimed last month that Iran had an unpaid debt for its construction services, and said that as a result construction might take longer than previously expected.
The Bushehr facility has been a source of international dispute, with the United States and other Western countries raising concerns that Iran could use the project as part of a covert weapons program. Iran has consistently denied that its nuclear program has military goals.
The UN Security Council adopted a resolution in December imposing sanctions against Iran.
Russia, a key economic partner of Iran, has consistently supported the Islamic Republic's right to nuclear power under the Nuclear Non-Proliferation Treaty (NPT), and has resisted the imposition of harsh sanctions.
