Security Hybridization: How Countries are Cooperating with Both the United States and China

September 11, 2025

Strauss Center Distinguished Scholar Dr. Sheena Chestnut Greitens was recently interviewed by the National Committee on US-China Relations for a webinar titledA New Era of Global Security: Why More Countries Are Cooperating with Both the U.S. and China.” In the interview, Dr. Greitens highlights the changing nature of security guarantees since the Cold War and what the long-term implications are for the United States.

“That overlap of China providing largely internally-focused security and the United States as an external security provider is what we call security hybridization,” states Dr. Greitens. “I think we need to acknowledge that there are places where the public security goods that China is providing are valuable and valued by other countries.”
