Breakthrough Starshot Program P&L: 0 (≃ 0 CNY)
This is quote directly from the program's original website:
The program to launch a nanocraft ++concept++, combining light beamer, lightsail and “StarChip,” - by far the most plausible system for launching a realistic mission to Alpha Centauri within a generation.
The key elements of the proposed system design are based on technology either already available or likely to be attainable in the near future under reasonable assumptions.
The program is managed by Avi Loeb, Pete Worden, et. al, - executives of the Breakthrough Initiatives.
