Is Shahryar's release linked to Anderson's release?

The childhood friend of Rajiv Gandhi, Adil Shahryar who was son of Mohammed Yunus, former Charmian of the Trade Fair Authority of India and once a possible presidential candidate was granted clemency by US President on June 11, 1985.

This happened six months and four days after Warren Anderson, CEO of Union Carbide Corporation (UCC) responsible for Bhopal disaster was released on payment of 25,000 after 6 hours although he was arrested for non-bailable offence by the Congress party led Madhya Pradesh and Government of India on December 7, 1984. Was it a coincidence?

Prime Minister Rajiv Gandhi visited USA from June 11 to June 15, 1985 during his 2 week trip to 5 countries and had discussions with Ronald Reagen. A joint statement was issued on June 15 referred to science and technology initiative that commenced in 1982 and extended it by 3 years on October 1985. He visited US for the second time in October 1987.

John Gunther Dean, US Ambassador to India met him on December 4, 1987. (Foreign policy of India, by N. Jayapalan, Atlantic Publishers & Dist). Did they discuss Bhopal disaster and UCC's liability?
