China has long-range planning and they plan to close their nuclear fuel cycle around 2050. It is a choice based upon economics and world uranium supplies.
The long-term solution is to store the waste on-site in dry casks with some separation and ramp up the construction of fast reactors or molten salt reactors and use all of the uranium 238 and plutonium to power the world for about 20 times longer than the 5% of the uranium (the 235 part) in the fuel rods that were already used (Table \ref{291135}).
What is left is stuff with short half-lives of 12 years or less. This material also is useful\cite{Wang_2011}.
