A senior Iranian lawmaker reiterated Tehran\'s commitment to the Non-Proliferation Treaty (NPT) rules and regulations, but meantime underlined that the country would not accept any undertakings beyond the treaty.\"We believe that our works regarding nuclear energy have been in compliance with the NPT rules and we accept no demand or move beyond it,\" member of the parliament\'s National Security and Foreign Policy Commission Evaz Heidarpour told FNA on Tuesday.He underlined Iran\'s need to use nuclear energy for medical, research and agricultural purposes, and announced that Tehran will continue its magnificent advancement in the nuclear energy industry.Heidarpour pointed to the talks between Tehran and the Group 5+1 (the five permanent UN Security Council members plus Germany) and the demand by the West for the suspension of Iran\'s nuclear activities, and noted, \"And if the G5+1 countries continue insisting on the suspension of Iran\'s activities, our country, similar to the past, will not accede to their irrational demands.\"Iran and the six world powers had 4 rounds of talks in Almaty, Kazakhstan, on April 5-6.The Iranian team was led by Saeed Jalili, who is also the Secretary of Iran\'s Supreme National Security Council (SNSC), and the G5+1\'s representatives were presided by EU foreign policy chief Catherine Ashton.Jalili told reporters after four rounds of talks with the six world powers in Kazakhstan that the sextet should accept to take reciprocal confidence-building measures if they mean to launch cooperation with Tehran, adding that the NPT should be the basis for such cooperation.\"The G5+1 offered some proposals in Almaty 1 (on February 26-27) which included different axes with different items. We studied them and put them under precise expert discussions in the Istanbul meeting (on March 17 to 18). What we presented in Almaty 2 included the point that some of these elements can be presented in the framework of an agreement for a first step, and we offered a proposal on the very same basis,\" Jalili said on Saturday.He said differences can exist, but negotiations should lead to agreements on the basis of common points, \"and this common basis can be the nuclear Non-Proliferation Treaty (NPT). They should recognize their undertakings with regard to the rights enshrined in the NPT, including the right of enrichment and use of the peaceful nuclear technology and this can be a basis for agreements\".Washington and its Western allies accuse Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program, while they have never presented any corroborative evidence to substantiate their allegations. Iran denies the charges and insists that its nuclear program is for peaceful purposes only.Tehran stresses that the country has always pursued a civilian path to provide power to the growing number of Iranian population, whose fossil fuel would eventually run dry.Despite the rules enshrined in the NPT entitling every member state, including Iran, to the right of uranium enrichment, Tehran is now under four rounds of UN Security Council sanctions for turning down West\'s calls to give up its right of uranium enrichment.
