China proposes its own mission to Apophis

Though it is not clear the Chinese government has approved the mission, Chinese scientists have now proposed a mission to to rendezvous with the potentially dangerous asteroid Apophis when it does its next close fly-by of the Earth in April 2029.
The mission would consist of two small satellites sent into a halo orbit around Sun-Earth Lagrange point 1 to await the approach of Apophis and transfer into a flyby orbit so as to meet the asteroid shortly after its close encounter with the Earth. The asteroid is due to pass within the geosynchronous orbit belt on Friday, April 13, 2029.
The Apophis mission would be added to a more ambitious larger asteroid mission, also not yet approved, dubbed CROWN, that would launch six spacecraft into “Venus-like, heliocentric orbits” where they would search and track Near-Earth Asteroids that are hard to spot because they are closer to the Sun than Earth.
China recently unveiled a blueprint to develop what it calls a “near-Earth asteroid defense system.” It appears the scientists for the project above are lobbying to get picked up as part of that blueprint. I should add that they first pushed this project in June, and three months later it still remains unfunded.
At present, there are many flying, planned, and proposed missions to reach Apophis during its 2029 fly-by. Osiris-Apex is on its way, having been repurposed after doing its sample return mission to Bennu. Europe is currently building its Ramses probe, which will also include two cubesats. Though other probes have been proposed, none have yet been approved.
