The US State Department said on Monday two senior diplomats are due to visit Sri Lanka later this month for talks about war crimes committed during the final months of the military conflict against the LTTE.
Assistant Secretary of State for Central and South Asian Affairs Robert O. Blake and Under Secretary of State for Civilian Security, Democracy and Human Rights, Maria Otero are visiting the island from February 12-14.
Issues to be discussed with Sri Lankan officials include "peace, accountability and reconciliation processes".
The visit comes just before the UN Human Rights Council Session commences in Geneva at the end of the month.
It is thought the US will push for a resolution to increase pressure on Sri Lanka to probe war crimes.
"The US is mounting pressure on us this time, but we should be able to get over the difficulties because we have strong support from India," a government source in Colombo told AFP on Sunday.
