With relations severed with Pakistan, Gaddafi normalized relations with India in 1978, and Gaddafi reached a mutual understanding with India for civil nuclear cooperation, as part of India's Atoms for Peace program. With the Indian Prime Minister Indira Gandhi visiting Libya in 1984, a nuclear energy pact was signed by Libya and India, but it is unclear how much interaction and cooperation took place. Throughout the 1980s, Libyan efforts continued to push for acquiring nuclear weapons from various sources. In an ingenious persuasion to uranium enrichment in 1978, Libya made an effort to gain access to uranium ore, uranium conversion facilities, and enrichment techniques that together would have enabled Libya to produce weapons-grade uranium. The approach failed in 1979, and in 1980 Libya decided to pursue a plutonium-based pathway to nuclear weapons. Libya imported 1,200 tons of uranium ore concentrate from French-controlled mines in Niger without declaring it to the IAEA, as required by its safeguards agreement. In 1982, Libya attempted to enter in an agreement with Belgium for purchasing a small plant for manufacturing UF4. At the time, Libya had no declared nuclear facilities that required UF4, and the purchase was refused.
