India and Pakistan exchanged lists of their nuclear installations and prisoners on 1 January 2026 under long-standing bilateral agreements. The annual exchange took place despite strained ties between the two neighbours after recent military hostilities. The nuclear list exchange is part of a pact that bars both sides from attacking each other’s atomic facilities. The prisoner list exchange is linked to a separate consular access arrangement.
Nuclear Installations Pact
The agreement on the prohibition of attacks against nuclear installations was signed on 31 December 1988 and entered into force on 27 January 1991. It requires both countries to share details of their nuclear installations and facilities every year on 1 January. The purpose is to reduce the risk of escalation and protect sensitive atomic infrastructure during periods of tension.
Annual Information Exchange
Under the pact, India and Pakistan exchange lists of covered nuclear sites through diplomatic channels. The practice has continued for more than three decades. Such exchanges are routine obligations under the bilateral framework and are separate from wider political or military developments between the two countries.
Prisoners Under Consular Access
Alongside the nuclear list, both sides also exchanged lists of prisoners in each other’s custody. Pakistan handed over a list of 257 Indian prisoners, including 199 fishermen and 58 civilians. The exchange is carried out twice a year, in January and July, under the consular access agreement signed on 21 May 2008. It is intended to improve communication on detention cases and facilitate consular contact.
Significance For Bilateral Relations
The exchange reflects the continued functioning of limited diplomatic mechanisms between India and Pakistan despite deep political and security tensions. It marks the role of formal agreements in managing sensitive issues such as nuclear safety, detainee information, and crisis stability.
