Nikki Haley, who is on a two-day visit to India, met Satyarthi at the 'Mukti Ashram', a short-term rehabilitation home for rescued children, here to discuss children's rights, human rights and security matters, according to a statement by Satyarthi's office.

Dubbing crimes against children as the "biggest crisis facing humanity currently", Satyarthi urged the highest ranking Indian-American in the Trump administration that an international response mechanism be formed under the aegis of the United Nations to address the issue.

"It is our collective responsibility to ensure that every child is safe and afforded every opportunity to have a full life. I look forward to sharing our commitment to end child trafficking," said Haley.

The two also discussed international problems pertaining to children's safety and rights. Haley also interacted at length with the children who had been rescued from various factories by Satyarthi's team at his NGO Bachpan Bachao Andolan," according to the statement.

"India and the US are two of the largest democracies in the world and should take collective responsibility for the protection of children," Satyarthi said.

Haley is on her first visit to India since becoming the US envoy to UN. She had earlier visited India in late 2014, when she was the South Carolina Governor.

Haley, the daughter of Sikh immigrants from Punjab, is the first Indian-American to serve in a Cabinet-level position in any US presidential administration.
