From 2002 through 2008, the Bush Administration denied funding to UNFPA that had already been allocated by the US Congress, partly on the refuted claims that the UNFPA supported Chinese government programs which include forced abortions and coercive sterilizations. In a letter from the Undersecretary of State for Political Affairs Nicholas Burns to Congress, the administration said it had determined that UNFPA’s support for China’s population program “facilitates (its) government’s coercive abortion program”, thus violating the Kemp-Kasten Amendment, which bans the use of United States aid to finance organizations that support or take part in managing a program of coercive abortion of sterilization.

What claims were not refuted?
