The markets seem to be rallying as the Russians dial down the Ukraine confrontation. After a couple of dips, it looks like we’re edging back into a risk-on mode, with Putin apparently deciding that he has what he needs and it’s time to back off.

That’s good news, but the situation in the South China Sea appears to be heating up again. Since I wrote about the rising level of confrontations between nations in 2012, nothing particularly noteworthy has happened. The problem has continued to grow, however, as China continues to press its claims, steadily deploying different means to make them concrete.

Now, we’ve reached another newsworthy moment in the Chinese expansion. Not one but two Chinese neighbors, Vietnam and the Philippines, have staged military confrontations to protest China’s actions in disputed territory.

The Vietnamese confrontation was prompted by China’s construction of a deep-water oil drilling rig in disputed waters—a fact on the ground that would help cement Chinese claims. The Philippines, on the other hand, seized Chinese ships carrying illegal sea turtles reportedly caught in their territory, which has sparked protests from Beijing and demands to release the crew, escalating it above a simple law enforcement action. Of these two, the Vietnamese situation is by far the more serious, but the sea turtle incident is typical of many other similar actions.

What’s the takeaway for investors?

Just as the Ukraine confrontation seemingly came out of the blue but in fact had deep roots, there are other potentially major geopolitical risks that investors should keep an eye on. And this time, they won’t be coming out of the blue.

Along with the U.S., East Asia is the major economic driver of the planet right now, and it is also politically fractured. Between China, Japan, and the Koreas, you have major economies, navies, and militaries facing each other across centuries of grudges and hostilities, complicated by growing competition for limited resources and a universal need to control sea lanes (and prevent others from controlling them instead).

Much attention has been paid to how “the end of history” has failed to materialize in Europe. I would argue that, as true as that has been, history never even slowed down in East Asia—and, in fact, it appears to be speeding up.
