A senior US official called for Sri Lanka to implement a "credible domestic" mechanism with "substantial involvement" from the international community.
US assistant secretary of state for South and Central Asian affairs Nisha Biswal told PTI that the Sri Lankan government had demonstrated "a very strong intent" in addressing rights concerns.
"It is fundamentally in the interest of the Sri Lankan people to secure the peace and prosperity of all of these citizens, and I think what motivates us is that hope and that desire to support a peaceful and prosperous Sri Lanka that brings opportunity for all its citizens," she said.
“It is a difficult process, it is a long process,” she added, saying “there will inevitably be setbacks”.
However, she said "we have seen that the government in the past nine months in office has done more to try to build trust and move the country towards a more inclusive society, than perhaps been done in the last nine years and beyond".
"That is an encouraging sign. It is a long road ahead for the country, for the government, for the President and for the people".
