President Barack Obama called modern day slavery "barbaric" and "evil" as he spoke out Tuesday against trafficking and praised companies, organizations and individuals fighting the traffickers.
He also signed an executive order strengthening protections against human trafficking for domestic federal contracts, and tightening anti-trafficking rules for government contracts abroad worth more than $500,000.
Speaking at the Clinton Global Initiative, Obama said: "It ought to concern every person, because it's a debasement of our common humanity. It ought to concern every community, because it tears at the social fabric.
"It ought to concern every business, because it distorts markets. It ought to concern every nation, because it endangers public health and fuels violence and organized crime.
"I’m talking about the injustice, the outrage, of human trafficking, which must be called by its true name–modern slavery."
The annual Trafficking in Persons Report - the world's most comprehensive resource of governmental anti-human trafficking efforts - was published Tuesday by the U.S. State Department.
It identifies countries that the U.S. says meet minimum standards of anti-trafficking efforts, countries working towards them and countries that appear to be doing little to stop trafficking.
The report is compiled with the help of U.S. embassies, non-governmental organizations, aid groups and individuals around the world.
Secretary of State Hillary Clinton said: “Ultimately, this report reminds us of the human cost of this crime. Traffickers prey on the hopes and dreams of those seeking a better life and our goal should be to put those hopes and dreams back within reach, whether it's getting a good job to send money home, to support a family, trying to get an education for one's self or for one's children or simply pursuing new opportunities that might lead to a better life.
Teenagers who once worked in India’s sex trade showed how dance is helping them leave their previous lives behind.
Five girls performed for U.S. Secretary of State Hillary Clinton during her visit to India.
They are part of Kolkata Sanved, a dance therapy movement founded in 2004 by Sohini Chakraborty, a dance sociologist and dance activist. It provides an alternative approach to therapy and healing for victims of violence and trafficking.
The 2011 Trafficking in Persons Report, produced by the State Department, said: “India does not fully comply with the minimum standards for the elimination of trafficking; however, it is making significant efforts to do so."

Washington (CNN) - Secretary of State Hillary Clinton and heads of various U.S. government departments made clear Thursday that preventing human trafficking is a priority of the Obama administration.
The 27 million men, women and children victims of human trafficking are an "affront to our most fundamental values," Clinton said at the annual meeting at the White House of the President's Interagency Task Force to Monitor and Combat Trafficking in Persons.
Clinton chaired the meeting of the task force, which is a Cabinet-level unit that coordinates federal efforts.
Those in attendance - including Attorney General Eric Holder, Secretary of Homeland Security Janet Napolitano and Director of National Intelligence James Clapper - highlighted recent successes and the new collaborative efforts to combat human trafficking around the world and on the domestic front.
"For us at the national security staff, this is a national security issue," said Deputy National Security Adviser Denis McDonough. "... Human trafficking is at the nexus of organized crime, is a source for funding for international terrorist groups, (and) is a source for funding for transnational terrorist groups. It fundamentally endangers international security."
In a panel hosted by CNN's Jim Clancy, anti-slavery activists speak out about what can and should be done.
