The United Front Work Department, an organ of the Chinese Communist Party's Central Committee.
It's the CCP's influence-routing body, running operations to shape politics inside target nations without open force.
It conducts diaspora management and elite capture in target countries and runs sub-kinetic (non-military) influence operations, including in U.S. local politics and diaspora mobilization.
It's the mechanism by which China projects political influence abroad below the level of open conflict. That makes it a quiet but real tool of foreign leverage.
