China plans to send a mission to Jupiter, currently scheduled for launch in 2029. So far the exact form and focus of the mission have not been specified. It is lilely to be called Tianwen 4

It has been reported that mission profiles are being considered:

Jupiter Callisto Orbiter, with an obvious focus on Callisto

and

Jupiter System Observer, with a focus on Io

For context, NASA will soon launch Europa Clipper, focusing on Europa, and ESA will launch JUICE, focusing on Ganymede, so the decison for CNSA is quite interesting.

This market will resolve when it is reliably reported than CNSA has confirmed the mission and confirmed a mission profile. If the mission is not approved it will resolve NA. If the mission is confirmed but neither mission profile is selected, it will resolve to NA, unless there is still an obvious focus on Callisto or Io, in which case it will resolve accordingly.

If the JSO profile is chosen, and China says there is a focus on Io, but actually the flightplan includes roughly similar numbers of close approaches to Callisto and Io, this market WILL resolve to JSO.
