Pakistan's President Asif Ali Zardari is set to go to India Sunday where he will meet with Indian Prime Minister Manmohan Singh in New Delhi. It will be the first visit to India by a Pakistani head of state since 2005.
The two nuclear-armed nations are seeking to normalize relations following the 2008 terror attacks in the Indian city of Mumbai.
However, Mr. Singh is widely expected to raise India's concerns about security and insist that Pakistan show its seriousness about reining in terrorist groups behind the Mumbai attacks. India has blamed the Lashkar-e-Taiba militant group for the attack.
Islamist Hafiz Saeed, suspected of masterminding the Mumbai attacks, operates openly in Pakistan. Last week, the United States placed a $10 million bounty on on Saeed.
Sunday's meeting of the two leaders comes a day after a massive avalanche hit a military complex in the mountainous Pakistan-controlled Kashmir region, near the Indian border. Up to 135 people are feared dead.
Pakistan and India each have thousands of troops stationed in Kashmir, which both nations claim in full. Territorial disputes over control of the rugged, mountainous region have sparked two wars between India and Pakistan.
