They can afford to take their time and do it right. The program is open-ended and they are under no pressure, certainly not from the West. Of course they wish to establish a manned presence in space as soon as reasonably possible, so they will press on. No doubt their funding will be increased as a result of their continued success.
There are people inside China opposing the manned space project. THey think the defense budget should be the first priority. BTW what did the US gain from the Moon landing?
