According to the MEA, the agreement requires India and Pakistan to inform each other of the nuclear installations and facilities covered under the pact on 1 January of every calendar year. Thursday’s exchange marked the 35th consecutive exchange of such lists, with the first taking place on 1 January 1992.The annual exchange has continued uninterrupted for over three decades, even during periods of heightened political and military tension between the two neighbours.

What the agreement says

The Agreement on the Prohibition of Attack against Nuclear Installations and Facilities was signed on 31 December 1988 and entered into force on 27 January 1991, following the exchange of instruments of ratification by both sides.Under the agreement, both India and Pakistan commit themselves to refrain from undertaking, encouraging or participating in any action aimed at causing destruction of, or damage to, nuclear installations or facilities in the other country.

The scope of the agreement is broad. Nuclear installations and facilities covered under the pact include nuclear power plants, research reactors, fuel fabrication units, uranium enrichment facilities, isotope separation plants, reprocessing units and sites storing significant quantities of radioactive material, whether fresh or irradiated.The agreement also specifies that both countries must exchange information on the locations of these facilities, typically in the form of latitude and longitude coordinates, once every year.

Why the annual exchange matters

The annual exchange of lists is designed to reduce the risk of accidental, miscalculated or deliberate attacks on sensitive nuclear infrastructure during periods of conflict or crisis.By formally identifying protected sites, the agreement seeks to prevent scenarios in which conventional military operations could inadvertently escalate into a nuclear crisis. An attack on a nuclear installation, even with conventional weapons, could have catastrophic humanitarian, environmental and strategic consequences.Security analysts view the exchange as a confidence-building measure that helps maintain a minimum level of predictability between two nuclear-armed neighbours with a long history of conflict.Notably, the exchange has continued even during times of strained relations, including after major crises such as the Kargil conflict, the 2001–02 military standoff, the 2016 Uri attack and the 2019 Pulwama attack and Balakot air strikes.
