TEHRAN (AFP/Reuters) - Irans atomic chief on Tuesday accused the new UN nuclear watchdog head, Yukiya Amano, of taking sides against Tehrans atomic programme but said he hoped the Japanese official would modify his stand. Ali Akbar Salehis criticism came as Moscow and Beijing - two veto-wielding powers at the UN Security Council - were divided over imposing new sanctions on Tehran. US Secretary of State Hillary Clinton also appeared to extend her timeline on fresh UN sanctions. We expected Amano to examine and adopt a position about the nuclear issue in an unbiased way, but unfortunately and in contradiction with what he had said before, we did not see an unbiased position, Salehi told AFP, reacting to comments from the watchdog chief on Monday. We hope that he will change his approach, Salehi said on the sidelines of a Tehran meeting of industry ministers of eight developing nations. Amano, who took over as head of the International Atomic Energy Agency (IAEA) on December 1, said in an address to the agencys board in Vienna that Iran is still not giving sufficient information on its nuclear activities. Irans parliament speaker Ali Larijani lashed out at Washington, saying its policy of double standards has affected (the credibility) of the IAEA. Larijani said Iran had handled the nuclear file with precision compared to the adventurist moves by Westerners, according to ISNA news agency. Amano, however, said a controversial IAEA-brokered deal to supply higher grade nuclear fuel for a Tehran research reactor was still on the table. Salehi said Iran was ready to sign up provided Tehran received necessary and enough guarantees. Salehi said the guarantee which Tehran insisted was that the exchange (of fuel) must happen simultaneously and inside Iran, adding such a condition was not illogical. Meanwhile, China stood its ground that diplomacy was the best way to resolve the standoff over Irans nuclear programme, as US diplomats arrived in Beijing on Tuesday.
