A report by the Taiwanese Defense Ministry states that China has placed surface-to-air missiles on the disputed Woody Island. Taiwanese President-elect Tsai Ing-wen called on all parties to "exercise self-control based on the principle of peaceful resolution of disputes in the South China Sea," while Harry B. Harris Jr., commander of the US Pacific Fleet, said that such a move would be "a militarization of the South China Sea in ways" that Mainland China's leader Xi Jinping had pledged not to make.
