Erm, according this chart, China has the following score:
Demographic Pressures: 7.7 (And for some reason, Japan, which has a demographic score of 4.7, despite Japan has 25% of its population as old people and China only has 9% of its population as old people. Norway is closer to China in term of the percentage of old people at 14% and Norway is given a score of 2.3)
Refugees and IDPs: 5.9 (I am trying to figure what exactly did this criteria got rated. Did it rated by total refugee population? Couldn't be, Germany has more refugee population than China and US has just about the same. German is given a score of 3.3 and US is given a score of 2.4. So, does this mean it is rated by per capita? Again, US is given a much lower score than China despite its has about 3 times more refugee per capita. Sometimes I really can't figure out these people.

Group Grievance: 8.6 (Eh, we all saw this from a mile away. I mean, how dare China grieve those poor HKers, you know, they should be like US, start a country wide riot of racial hate and then they will be given a score like US, which is...4.5 /sarcasm off)
Human Flight: 4.8 (Not sure how this is calculated.)
Uneven Development: 7.7 (Afghanistan is given a score of 7.5. Which means the site believes Afghanistan is more evenly developed than China. I don't think I need to say more.)
Poverty and Economic Decline: 3.9 (Japan is even a score of 3.6. I think 220% of public debt to GDP means it is doing swimmingly well.)
Legitimacy of the State: 7.9 (Dear Editor, in case you have not noticed. The legitimacy of a government is only decided by the group of people it governs, not someone else.)
Public Services: 6.5 (According to the site, Egypt has a public service of 5.7. You know, after the whole revolution and stuff)
Human Rights: 9.1 (Again, Afghanistan is given a score of 8.3. I guess the improvised explosives are very humane indeed.)
Security Apparatus: 6.2 (not sure what is this one supposed to be)
Factionalized Elites: 7.2 (Japan's score of 2.6 really shows that how you can has a Zaibatsu run government and still have the gullible foreigners eat it up)
External Intervention: 3.5 (Singapore has a score of 2.0. Apparently, there are wonderful people out there believe it is easier to militarily invade China than Singapore.)
To sum it up, I would call the list bullshit.
