The defense secretaries of India and Pakistan are meeting for two days of talks about how to reduce their troops above the mountainous Siachen Glacier, the world's highest battlefield.
The meeting began Monday in New Delhi and is part of a peace dialogue between the long-time rival neighboring countries.
Military experts say Siachen's inhospitable climate and avalanche-prone terrain have claimed more lives than gunfire.
India has decided to proceed with the meeting despite testimony by a Pakistani-American on trial in Chicago last week who said Pakistan intelligence was involved with the terrorist group that attacked Mumbai in 2008, leaving 166 people dead.
India suspended peace talks following the Mumbai attacks, but the two nuclear powers have since taken some tentative steps to revive the peace process.
India has long accused Pakistan of harboring the militants who carried out the Mumbai attack.
Indian and Pakistan have gone to war three times since 1947.
