In 1989, Benazir Bhutto made a quick visit in the U.S. asking U.S. to stop financing the Afghan mujahideen to President George H. W. Bush, which she marked "America's Frankenstein". This was followed by Nawaz Sharif who visited the U.S. in 1990, but U.S. gave cold shoulder to Pakistan, asking Pakistan to stop developing the nuclear deterrence. In 1990, Prime minister Nawaz Sharif travelled to the U.S. to solve the nuclear crises after the U.S. had tightened its economic embargo on Pakistan, prompting Sharif and then-Treasure Minister Sartaj Aziz to hold talks on Washington. It was widely reported in Pakistan that the U.S. Assistant Secretary of State Teresita Schaffer had told the Foreign Minister Shahabzada Yaqub Khan to halt the uranium enrichment programme. In December 1990, France's Commissariat à l'énergie atomique agreed to provide a commercial 900MW power plant, but plans did not materialize as France wanted Pakistan to provide entire financial funds for the plant. Furthermore, the U.S. Ambassador Robert Oakley further influenced on the project, showing growing concerns of the U.S. on the agreement. While talking to U.S. media, Nawaz Sharif declared that: "Pakistan possessed no bomb... Pakistan would be happy to sign the Nuclear Nonproliferation Treaty (NPT) but it must be provided "first" to India to do the same". After France's project was cancelled, Nawaz Sharif successfully held talks with the China to build the largest commercial nuclear plant, CHASNUPP-I in Chasma city in Pakistan.
