The leaders of India and Pakistan have said that peace between the two nuclear rivals is "irreversible". Manmohan Singh and Pervez Musharraf were speaking after signing a joint statement that followed peace talks in the Indian capital, Delhi. They have also agreed to increase trade and transport links between Indian- and Pakistani-administered Kashmir aimed at solving the long-running dispute. The two sides embarked on a peace process in January last year. President Musharraf left India for the Philippines after calling on former Indian Prime Minister, Atal Behari Vajpayee.
