China therefore constantly postures as if it were going to send large numbers of forces into Pakistan, but in the end, the Pakistanis have no interest in de facto Chinese occupation -- even if the occupation were directed against India. The Chinese likewise are not interested in undertaking security operations in Pakistan. The Indians have little interest in sending forces into Tibet in the event of a Tibetan revolution. For India, an independent Tibet without Chinese forces would be interesting, but a Tibet where the Indians would have to commit significant forces would not be. As much as the Tibetans represent a problem for China, the problem is manageable. Tibetan insurgents might receive some minimal encouragement and support from India, but not to a degree that would threaten Chinese control.
So long as the internal problems in Han China are manageable, so is Chinese domination of the buffer states, albeit with some effort and some damage to China's reputation abroad.
The key for China is maintaining interior stability. If this portion of Han China destabilizes, control of the buffers becomes impossible. Maintaining interior stability requires the transfer of resources, which in turn requires continued robust growth of the Chinese coastal economy to generate the capital to transfer inland. Should exports stop flowing out and raw materials in, incomes in the interior would quickly fall to politically explosive levels. (China today is far from revolution, but social tensions are increasing, and China must use its security apparatus and the People's Liberation Army to control these tensions.)
Maintaining those flows is a considerable challenge. The very model of employment and market share over profitability misallocates scores of resources and breaks the normally self-regulating link between supply and demand. One of the more disruptive results is inflation, which alternatively raises the costs of subsidizing the interior while eroding China's competitiveness with other low-cost global exporters.
For the Chinese, this represents a strategic challenge, a challenge that can only be countered by increasing the profitability on Chinese economic activity. This is nearly impossible for low value-added producers. The solution is to begin manufacturing higher value-added products (fewer shoes, more cars), but this necessitates a different sort of work force, one with years more education and training than the average Chinese coastal inhabitant, much less someone from the interior. It also requires direct competition with the well-established economies of Japan, Germany and the United States. This is the strategic battleground that China must attack if it is to maintain its stability.
A Military Component
Besides the issues with its economic model, China also faces a primarily military problem. China depends on the high seas to survive. The configuration of the South China Sea and the East China Sea render China relatively easy to blockade. The East China Sea is enclosed on a line from Korea to Japan to Taiwan, with a string of islands between Japan and Taiwan. The South China Sea is even more enclosed on a line from Taiwan to the Philippines, and from Indonesia to Singapore. Beijing's single greatest strategic concern is that the United States would impose a blockade on China, not by positioning its 7th Fleet inside the two island barriers but outside them. From there, the United States could compel China to send its naval forces far away from the mainland to force an opening -- and encounter U.S. warships -- and still be able to close off China's exits.
That China does not have a navy capable of challenging the United States compounds the problem. China is still in the process of completing its first aircraft carrier; indeed, its navy is insufficient in size and quality to challenge the United States. But naval hardware is not China's greatest challenge. The United States commissioned its first aircraft carrier in 1922 and has been refining both carrier aviation and battle group tactics ever since. Developing admirals and staffs capable of commanding carrier battle groups takes generations. Since the Chinese have never had a carrier battle group in the first place, they have never had an admiral commanding a carrier battle group.
China understands this problem and has chosen a different strategy to deter a U.S. naval blockade: anti-ship missiles capable of engaging and perhaps penetrating U.S. carrier defensive systems, along with a substantial submarine presence. The United States has no desire to engage the Chinese at all, but were this to change, the Chinese response would be fraught with difficulty.
