Pakistani and Indian officials began two days of talks in Islamabad Tuesday, focusing on nuclear confidence-building measures.
Pakistani Foreign Ministry spokesman Masood Khan said experts from both sides are discussing "new safeguards to avoid any accidental nuclear war."
He said at their first expert-level meeting in New Delhi in June, the two sides recognized the need to work for, what he called, strategic stability in the region.
Observers say the talks may lead to a formal agreement on informing each other in advance of their frequent missile tests, a practice both countries already follow informally.
The meeting in Islamabad is part of a peace process India and Pakistan began earlier this year to resolve long-running disputes, including the thorny issue of Kashmir.
