Mian Muhammad Nawaz Sharif (Urdu/Punjabi: myN mHmd nwz shryf, born 25 December 1949) is a Pakistani businessman and politician who served as the Prime Minister of Pakistan from 2013 until he was disqualified for life from office by the Supreme Court of Pakistan in 2017. He had previously served as the Prime Minister twice in the 90s (1990-93 and 1997-99) and the Chief Minister of Punjab from 1985 to 1990. He is Pakistan's longest-serving prime minister. Born into the upper-middle class Sharif family in Lahore, he is the son of Ittefaq and Sharif Group founder, Muhammad Sharif, and the elder-brother of three-time elected Punjab Chief Minister, Shehbaz.

On 7 November 1990, the newly elected prime minister announced his nuclear policy and in public television, Sharif responded that: "The peaceful [atomic] programme of which... it would be accelerated to accommodate growing [nuclear] [e]nergy needs and to make up for rising [oil] prices. And, of course, (Pakistan) will to construct new nuclear power plants." On 26 November, Sharif authorised talks with the US to solve the nuclear crises after the US had tightened its embargo on Pakistan, prompting Sharif to send his government's Treasure Minister Sartaj Aziz to held talks on Washington. It was widely reported in Pakistan that the US Assistant Secretary of State Teresita Schaffer had told the Foreign Minister Shahabzada Yaqub Khan to halt the uranium enrichment programme.  In December, France's Commissariat a l'energie atomique agreed to provide a commercial 900MW power plant, but plans did not materialise as France wanted Pakistan to provide entire financial funds for the plant. On December, the financial embargo was placed and the country's economy felt a distress that prompted Sharif to replace his Treasure minister. Sharif then used Munir Ahmad Khan to have convinced IAEA to allow Pakistan for a nuclear plant in Chashman where Khan intensively lobbied in IAEA for the nuclear power plant. In December 1990, IAEA allowed Pakistan to established CHASNUPP-I, signed with China; the IAEA also gave approval of upgrading of the KANUPP-I in 1990. During his first term, Sharif intensified his non-nuclear weapon policy and strictly followed the policy of deliberate nuclear ambiguity which was also continued by Benazir as well. Responding to US embargo, Sharif publicly announced that: "Pakistan possessed no [atomic] bomb... Pakistan would be happy to sign the Nuclear Nonproliferation Treaty (NPT) but it must be provided "first" to India to do the same."  Sharif intensified his move to enhance the Pakistan's integrated nuclear development and authorised projects that seemed to be important in his point of views. Sharif also promoted the peaceful nuclear energy programme, and signed the CHASNUPP-I reactor with People's Republic of China for the commercial electricity use. Sharif also responded to use the nuclear development in more of economical usage, benefited for the country's economy and its extension to the civil society. His policies to make the nuclear program for economical use was also continued by Benazir Bhutto and Pervez Musharraf. Answer this question using a quote from the following article:
