Based on the reference provided, Michael Chen is associated with UNICEF USA. The reference does not explicitly state that he is the CFO, but the information suggests a close connection.
Analysis
It's important to clarify that UNICEF USA is a separate entity that supports UNICEF's global mission. While the reference confirms Michael Chen's association with UNICEF USA, it does not definitively state that he is the CFO of the global UNICEF organization.
Therefore, while we can confirm his role within UNICEF USA, more information is needed to confirm if he is the CFO of the entire UNICEF organization.
