Eurasia Group founder Ian Bremmer has a long piece in the new issue of The National Interest that foretells continued political stability in China in spite of all the recent turbulence in the international system and at home. After cataloging various messes of the past few years—the global financial crisis and U.S. recession, war in Syria, and unrest in the other BRICS, to name a few—Bremmer says

It is all the more remarkable that there’s been so little noise from China, especially since the rising giant has experienced a once-in-a-decade leadership transition, slowing growth and a show trial involving one of the country’s best-known political personalities—all in just the past few months.

Given that Europe and America, China’s largest trade partners, are still struggling to recover their footing, growth is slowing across much of the once-dynamic developing world, and the pace of economic and social change within China itself is gathering speed, it’s easy to wonder if this moment is merely the calm before China’s storm.

Don’t bet on it. For the moment, China is more stable and resilient than many realize, and its political leaders have the tools and resources they need to manage a cooling economy and contain the unrest it might provoke.

Me, I’m not so sure. Every time I peek under another corner of the “authoritarian stability” narrative that blankets many discussions of China, I feel like I see another mess in the making.

• In 2013, ethno-nationalist unrest has hotted up in Xinjiang, Inner Mongolia, and Tibet.
• Air pollution has reached astonishing levels in many cities and only seems to keep getting worse, and people are talking more openly about it than they have in the past.
• Rising rates of bankruptcies and debt write-offs hint at the fragility of the financial pillar on which the remarkable economic growth of recent years stands.
• Land grabs by Chinese officials—another pillar of that economic edifice—continue to spur mass protests that sometimes turn violent, as does the pollution from the industrial plants that sometimes goes up on those seized plots.
• China’s population is now predominantly urban and rapidly becoming more so, and as political scientist Jeremy Wallace shows, urban concentration increases the risk of regime-threatening unrest, mostly by facilitating collective action.
• China also gets hit with a lot of natural disasters, and citizens aren’t always happy with the government’s response to those calamaties.

That list is not exhaustive. No one of these situations seems especially likely to turn into a full-blown rebellion very soon, but that doesn’t mean that rebellion in China remains unlikely. That might sound like a contradiction, but it isn’t.

To see why, it helps to think statistically. Because of its size and complexity, China is like a big machine with lots of different modules, any one of which could break down and potentially set off a systemic failure. Think of the prospects for failure in each of those modules as an annual draw from a deck of cards: pull the ace of spades and you get a rebellion; pull anything else and you get more of the same. At 51:1 or about 2 percent, the chances that any one module will fail are quite small. If there are ten modules, though, you’re repeating the draw ten times, and your chances of pulling the ace of spades at least once (assuming the draws are independent) are more like 20 percent than 2. Increase the chances in any one draw—say, count both the king and the ace of spades as a “hit”—and the cumulative probability goes up accordingly. In short, when the risks are additive as I think they are here, it doesn’t take a ton of small probabilities to accumulate into a pretty sizable risk at the systemic level.

What’s more, the likelihoods of these particular events are actually connected in ways that further increase the chances of systemic trouble. As social movement theorists like Sidney Tarrow and Marc Beissinger have shown, successful mobilization in one part of an interconnected system can increase the likelihood of more action elsewhere by changing would-be rebels’ beliefs about the vulnerability of the system, and by starting to change the system itself.

As Bremmer points out, the Communist Party of China has done a remarkable job sustaining its political authority and goosing economic growth as long as it has. One important source of that success has been the Party’s willingness and capacity to learn and adapt as it goes, as evidenced by its sophisticated and always-evolving approach to censorship of social media and its increasing willingness to acknowledge and try to improve on its poor performance on things like air pollution and natural disasters.

Still, when I think of all the ways that system could start to fail and catalog the signs of increased stress on so many of those fronts, I have to conclude that the chances of a wider crisis in China are no longer so small and will only continue to grow. If Bremmer wanted to put a friendly wager on the prospect that China will be governed more or less as it is today to and through the Communist Party’s next National Congress, I’d take that bet.
