Does China possess the technical ability to develop MIRV technology for ICBM?

I thought China knows the US warhead W-88, which is an MIRV tech... according to the Cox report.

Quite many experts seem to think that Cox report is mainly fear mongering.

The final test series concluded in the spring and summer of 1996. Overall, the yields since 1990 have suggested that two warheads have been in development: one in the 100-300 kt range, and one in the 600-700 kt range.

100-300kt warhead is probably the MIRV one and the bigger is for original DF-31. If you look pics of DF-31A you can see that it has a shroud and that makes it impossible to say if it carries more than one RV.

Here is interesting estimation of DF-31 RV weight from 1996.

The following assumptions were made to constrain the SD-stage modifications. First, only the minimum number of changes would be allowed to the stage to get the job done. The system would not be needed for range extension since the missiles which would most likely use this system, the Mod CSS-4 and the DF-41, would have sufficient range already. The system would deploy three 470-kg Dong Feng 31 (DF-31) RVs. The system would not contain penetration aids (penaids). In addition, all 12 pitch/yaw thrusters would be used for axial thrust. Furthermore, it was assumed that these 70 N thrusters could withstand the full 128 second continuous burn. Additionally, the modified SD stage would have 20 degree/second rotation and turn rate. Lastly, the payload shroud would have a mass of about 200 kg and would be jettisoned early during second stage burn.
