I happened to remember a few years ago (in late 2012), when Russia had completely disallowed US citizens to adopt Russian children due to 19 of them dying under US adopive parents' care.
RT article on the ban
Another RT article cites how kids are being sold due to shady "rehomings".
The Dima Yakovlev Law bans citizens of the United States from adopting children from Russia. The law was signed by Russian President Vladimir Putin on 28 December 2012 and took effect on 1 January 2013.
Remember that Clinton's final day as secretary was February 1, 2013.
Here's a gawker article on How Parents Use Facebook and Yahoo to Unload Adopted Kids Online
Looking into rehomings, I found Wasatch International Adoptions, which is the one found in this wikileaks email:
A Wasatch International employee is quoted:
Even though child trafficking is a major concern for Moyes she worries about the immediate help children need trapped In the rubble from a country in ruins. "How long will that child survive without somebody rescuing them," Moyes said.
It has a product page of the children available for rehoming
It also has a page for international children (including Haiti) and lists it's fees. For Haiti, it's $13,000-15,000 per child just for the foreign orphanage. The other costs add up to at least $10,000.
Other home stay agencies listing children for home stays.
Open Homes and Hearts offers children for 3-4 weeks for $2800
Guglielmo's hope offers home stays for $2900 (including children from Colombia or Ukraine)
Not sure about these leads, but the fact that Russia has banned us citizens and agencies from adopting their kids is telling. What do they know that we don't?
