I would like to give an answer to your question. There is not one country in the world that "supports" human trafficking. Every country has laws against it, it's just difficult in many places to do much about it because it is so rampant... even here in America. Although it is more prevalent in places such as India, Thailand and Cambodia... the problem exists all over the world. So again, in answer to your question - no country supports human trafficking. It is up to us - each one of us as individuals to do whatever we can to fight this fight against the worst atrocity in our society today. If interested, you can ready my blog at www.blog.joy.org
I just started a Hub Page about this today and will hopefully have some content in the next few days.
It's when people just like you become a voice against this cause and begin to speak out, that things begin to happen. We must join forces as a civilized society in order to win this battle. Many blessings to you...
