I’m sure that China is worried about a finger-waving harangue from John Kerry.

Taiwan’s Defense Ministry said the missile batteries had been set up on Woody Island in the Paracels chain, which has been under Chinese control for decades but also is claimed by Taiwan and Vietnam.

A U.S. defense official also confirmed the “apparent deployment” of the missiles, first reported by Fox News.

“There is every evidence, every day that there has been an increase of militarization of one kind or another,” Kerry told reporters when asked about the reported deployment. “It’s of serious concern.

“We have had these conversations with the Chinese and I am confident that over the next days we will have further very serious conversation on this.”
