India-Pakistan Nuclear Exchange: A Tradition of Safety

India and Pakistan have upheld a vital diplomatic tradition concerning nuclear safety by exchanging lists of their nuclear installations and facilities. This ongoing practice embodies a confidence-building mechanism aimed at mitigating risks and ensuring strategic stability in South Asia.

Recent Developments

On January 1, 2023, India and Pakistan exchanged their lists of nuclear installations, as mandated by a bilateral agreement. This simultaneous exchange, conducted in New Delhi and Islamabad, marks the 35th consecutive year of compliance with the agreement designed to prevent attacks on nuclear facilities.

About the Agreement

The exchanges occur under the Agreement on the Prohibition of Attack against Nuclear Installations and Facilities. Signed on December 31, 1988, and effective from January 27, 1991, this agreement obligates both nations to inform each other annually about their nuclear installations and facilities included under the treaty.

Key Features of the Agreement

  • The agreement prohibits either country from attacking or aiding in attacks on nuclear installations.
  • Both countries are required to exchange updated lists of these facilities every year on January 1.
  • This mechanism encompasses both civilian and strategic nuclear installations, thereby minimizing miscalculations and misunderstandings during tense periods.

2025 Exchange Details

The latest exchange was successfully conducted through diplomatic channels in both New Delhi and Islamabad. According to the Ministry of External Affairs, this exchange marks the 35th consecutive occurrence since the inaugural exchange on January 1, 1992, underscoring the commitment to agreed nuclear confidence-building measures.

Significance for Bilateral Relations

Despite politically strained relations, this annual exchange exemplifies that both nations continue to respect critical safety-oriented agreements. It plays a pivotal role in maintaining strategic restraint, lowering the risk of accidental escalation, and promoting regional nuclear stability, especially as both nations are nuclear-armed.

India-Pakistan Nuclear Confidence-Building Measures

Confidence-Building Measures (CBMs) aim to diminish mistrust between rival nations. India and Pakistan have implemented several nuclear CBMs, including advance notifications of ballistic missile tests and direct communication hotlines between military officials. The exchange of nuclear installations lists stands out as one of the oldest and most consistently adhered to CBMs between the two countries.
