Relations between India and Pakistan became more tense beginning in the early 1990s. Diplomatic talks between the two countries broke down in January 1994 over the disputed Kashmīr region.

Tensions escalated further in 1998, when India conducted several nuclear tests. Pakistan responded with its own tests, detonating nuclear weapons for the first time in its history. The Pakistani government then declared a state of emergency, invoking constitutional provisions that operate when Pakistan’s security comes under “threat of external aggression.” Many foreign countries, including the United States, imposed economic sanctions against both India and Pakistan for exploding nuclear devices.
