There’s something missing from the Defense Department’s new report to Congress on “Military and Security Developments” relating to China — and it’s something big. The 83-page report, which focuses on the Chinese military and Beijing’s concerns about Taiwan, makes no reference to the global outreach that extends across Asia and Africa and across the Pacific to Latin America. This outreach combines general trade and investment with arms sales and political patronage, threads that can sometimes be difficult to separate. But arms and politics very often are intertwined with “peaceful” commerce; detecting the junctures at which they become “security developments” is what analysis is for. An entire facet of China’s grand strategy has simply been left out of this report.

Search the document, and you will find no reference to China’s “String of Pearls” strategy of cultivating relationships — along with the potential for surveillance outposts and naval bases –across the Indian Ocean and South China Sea. Not a word is uttered about China’s much-remarked courtship with Latin America, which encompasses extensive military-to-military exchanges and arms sales along with the commercial operations of companies linked to the Chinese military. The ties in question include an ongoing effort to bolster military cooperation with Cuba, with which China has agreements to use signals-monitoring facilities against the United States. They also include a very unusual visit by Chinese warships to Chile, Peru, and Ecuador in late 2009.

The Mediterranean saw such visits for the first time this summer, conducted by Chinese warships departing their anti-piracy station near Somalia. China appears to be contemplating a naval base in Djibouti, but that’s the least of its inroads in Africa. Besides arming the homicidal rulers of Sudan and Zimbabwe (here and here), China is pursuing the same policy it has executed in Latin America of promoting arms sales and military-to-military exchanges. As this summary indicates, moreover, Africa’s unique characteristics make it a special proving ground for China’s dual-purpose (commercial and military) industries.

Ignoring this Chinese pattern when considering “security developments” is quite peculiar. In fact, the report’s principal thematic shortcoming is that it evaluates only one security issue — the status of Taiwan — in terms of its geostrategic features and implications. China’s other security issues are grouped abstractly as “flashpoints” and generic interests, creating the impression that North Korea is basically the same kind of problem for China as Pakistan, Iran, or the Spratly Islands.

But China, a nation facing long armed borders and disputed archipelagos in every direction, lacks the latitude Americans have to cast its problems in terms of political abstractions. China’s approach is based firmly on geography and power relationships. North Korea, Pakistan, and Taiwan are all different types of security concerns for China, as are India, the waterways of the Middle East, and the U.S. Navy.

Meanwhile, the Chinese regularly accuse the U.S., which they see as China’s chief rival in virtually every dimension, of “hegemonism and power politics.” This is not an abstraction for them; when they say this, they have in mind the pillars of U.S. security in the Eastern hemisphere: alliances, military presence, and declared interests, from one spot on the map to the next. China’s frame of reference for all its security calculations is U.S. military power, a fact that has more explanatory value for Beijing’s military build-up than any other.

If these factors go unacknowledged, we are in danger of supposing that China is arming itself to the teeth because of the Taiwan issue. Accept at face value China’s own statements about “threats” to its trade, throw in a public-spirited aspiration to support UN peacekeeping operations, and you get a DoD report in which the analysis comes off as strikingly fatuous. Having almost no reference to geography, the perceived rivalry with the U.S., or the political and security dimensions of China’s global outreach, it ends up being misleading as well.
