I want to know the answer to the following question:
What in the Chinese program caused trouble for UNFPA?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: no
