The US Ambassador to the United Nations Samantha Power, who is on a three-day visit to the country, appealed for support to the Sri Lankan government's reconciliation efforts.
In a tweet, she said, "Urged Jaffna Chief Minister Wigneswaran to help reinforce SriLanka precious moment for reconciliation/rebuilding."
Power met with local government officials in Jaffna and organisations and communities affected by the conflict.
Northern Province Chief Minister C. V. Wigneswaran during his meeting with US Ambassador to the United Nations Samantha Power, raised a number of issues concerning political prisoners, land rights and military presence in Jaffna.
Power will meet President Maithripala Sirisena and Prime Minister Ranil Wickremesinghe today.
US has expressed support for several steps taken by the present government under President Maithripala Sirisena to achieve reconciliation with the Tamil minority.
Several confidence-building-measures such as the release of Tamils-owned lands, lifting of travel restrictions to the North and de-escalating the military presence have been taken since January.
Lanka's main Tamil political party has accepted the government efforts to ensure reconciliation after three decades of ethnic war that claimed over 100,000 lives.
