You have to dig to the last page of a specialized newsletter -- but it's there -- the new UNICEF-Uzbekistan Newsletter contains a single paragraph at the bottom of the final page of the newsletter on forced child labour:
During the period of 17 to 22 September 2011, 6 teams consisting of 14 UNICEF staff members visited cotton fields in Fergana, Namangan, Andijan, Navoi, Bhukara, Khorezm, Karakalpakstan, Samarkand, Jizzak, Tashkent, Surkhandarya, and Kashkadarya regions. UNICEF’s observations regarding the use of children in the cotton fields were shared in the form of an update and a final report with the Cabinet of Ministers and the Ministry of Foreign Affairs. UNICEF continues to act and advocate at all levels of governance and society for the progressive elimination of child labour in cotton production.
The statement is couched in cautious terms so as not to actually make a formal finding and a condemnation about forced child labour.
Instead, UNICEF prefers to speak in positive terms about the "progressive elimination" of child labour.
While UNICEF quietly provides copies of its reports to the US and other governments, the report is not made available to the public.
