"Sri Lanka remains committed to pursuing the implementation of the recommendations of its domestic reconciliation mechanism, the LLRC," a government statement at the UN Human Rights Council sessions in Geneva has said.
"Indeed, as we have already indicated, some of the recommendations are already in a stage of implementation," Sri Lanka's permanent representative Ravinatha Aryasinha has said in his address at the UNHRC's ongoing 20th sessions.
In the previous UNHRC sessions held in March, the council adopted a resolution sponsored by the US and backed by India, urging Sri Lanka for expeditious implementation of the recommendations of the Lessons Learnt and Reconciliatation Commission (LLRC) in order to achieve reconciliation with the Tamil minority.
Aryasinha in his address branded the resolution ill-conceived, completely unnecessary and unwarranted.
"It does not add any value to the ongoing domestic efforts. On the contrary, this action has caused mistrust about international processes among the people of Sri Lanka and runs counter to our domestic efforts.
"We are mindful of these concerns of our people, and will therefore resolutely pursue a home grown solution on reconciliation which has their endorsement," he said.
