On February 9, 2013, China Review News republished an article originally from the World Journal (www.worldjournal.com) titled “The PLA Lays Sea Mines Three-dimensionally in Four Approaches; Locking Japan in Is as Easy as Turning over the Palm.” According to the article, with the possible escalation of the confrontation over the Diaoyu Islands (Senkaku Islands in Japan) and Huangyan Island (Scarborough Shoal in the Philippines), the Chinese navy may start sea mine warfare in the East China Sea or the South China Sea.
At the end of January, China Navy (http://navy.81.cn/), a PLA official website, revealed that a submarine detachment from the South China Sea fleet held a drill on placing sea mines to block water passages. Once a war breaks out, the Chinese Navy can lay sea mines quickly and secretly using submarines. The powerful “Sea Mines Field” would be able to surround American and Japanese warships within a certain area. The Chinese Navy will then severely attack American and Japanese warships with multiple anti-ship missiles from a shore base and an air base.
