Analogous to how Sister Cities International conducts citizen diplomacy by developing municipal partnerships between cities throughout the world, the US-China Common Concern Committee (UC4) is seeking to create cross-border partnerships among local, regional, and national organizations working on areas of global common concern. Whether we’re creating dialog between health clinics in Houston and Chengdu or solar energy startups in Silicon Valley and Shenzhen, the UC4 will engage in the art of cementing partnerships between the United States and China which can withstand the winds of change.
