I joined the conversation over the Asia Society’s ChinaFile on tensions between the China, the United States and Japan.

Specifically, I addressed a question “will China attempt to take the Senkakus by force?”

Let me pick up on Isaac’s first question, “will China attempt to take the Senkakus by force?”

Iain Johnston and I recently analyzed data on the frequency of Chinese Coast Guard patrols within the twelve nautical mile territorial waters of the islands. Since September 2012, China has used these patrols to challenge Japan’s sovereignty and administration of these disputed rocks.

For the past six months, however, China has reduced significantly the frequency of patrols it conducts within the island’s territorial waters. Before October 2013, it conducted a patrol roughly once per week, on average. Since then, it has conducted a patrol once every two weeks. In sum, the rate of patrols has dropped by half—and is statistically significant.

The reduced frequency of these patrols is noteworthy for several reasons. First, as Iain and I suggested, China may be signaling limits on its willingness to escalate, at least for now. Second, by reducing the number of patrols, China is also reducing the opportunities for an accident or incident to occur between Chinese and Japanese ships. Such an event, especially if it involved fatalities, could spark a much more intense crisis and greater incentives to use force on both sides.

Turning to Isaac’s question, the reduction in the frequency of these patrols is inconsistent with an escalation of pressure that might culminate in a decision by China to use force. Instead, China appears to have adopted a long-term view of dispute that does not involve taking them by force. Last summer, for example, a meeting of prominent Chinese government analysts concluded that China should “avoid an incident that sparks a war” over the islands. They also assessed that the dispute would persist for a long time to come and that it was therefore urgent to reduce the possibility and risk of a collision at sea.

Finally, a broader point. If China seized islands by force, they would be nearly impossible to defend from a counter-attack, as Gen. John Wissler noted; Moreover, a counter-attack to retake the islands would risk a much wider war, which China as well as the United States and Japan want to avoid.China’s leaders have quite likely anticipated such a scenario, which explains the emphasis on a long-term effort to challenge Japan’s control of the islands and surrounding waters with its coast guard and not its naval forces.
