New Delhi, Nov 25 (ANI): Union Trade Minister Anand Sharma on Monday welcomed the signing of the nuclear agreement between Iran, US and its allies, saying that it will bring peace and stability in the region. Iran and six world powers reached a breakthrough deal early on Sunday to curb Tehran's nuclear programme in exchange for limited sanctions relief, in what could be the first sign of an emerging rapprochement between the Islamic state and the West. Sharma, while speaking to mediapersons in New Delhi, said that Iran was a long-term ally and predicted consistent and strong trade relations between the countries.
