India and Pakistan continued their long-standing tradition of exchanging lists of nuclear installations on January 1, 2026. This yearly exchange follows a bilateral agreement that prohibits either side from attacking the other's nuclear sites. The Ministry of External Affairs (MEA) confirmed that this 35th consecutive exchange occurred simultaneously through diplomatic channels in New Delhi and Islamabad. The agreement was originally signed on December 31, 1988, and came into force on January 27, 1991. It requires India and Pakistan to share details of their nuclear facilities annually on the first day of January. Despite the tense relationship and recent four-day military clashes in May 2025, the pact remains in place. The MEA stated, "India and Pakistan today exchanged, through diplomatic channels, simultaneously at New Delhi and Islamabad, the list of nuclear installations and facilities, covered under the agreement on the prohibition of attack against nuclear installations and facilities between India and Pakistan." This exchange underscores the importance both countries place on maintaining certain safeguards amid ongoing challenges. This act continues a practice that began on January 1, 1992, illustrating a rare area of cooperation between the two neighbors amid otherwise strained ties.
