A few weeks ago the Yomiuri News on-line reported the following:
It became clear that the China Maritime Police Bureau, which performed monitoring activities at the East China Sea and South China Sea, was advancing a plan to construct a large base at China’s coast region in the coastal city of Wenzhou in Zhejiang province.
Official ships judged to be dispatched around Senkaku Islands and the Okinawa prefecture would be anchored here for the purpose of repairing, checking and crew training. Although tensions had eased with the resumption of private exchange developing between China and Japan, the Xi Jiping administration was holding a stance of no back down in his insistence over the sovereignty right at the East China Sea, and continued to dispatch official ships to strengthen the stance.
In a China Maritime Police Bureau meeting held in earlier this month in Wenzhou city, the contents related to the construction of a base appeared in the home page of Zhejiang Province. According to that, the planned "Wenzhou overall security commanding base" had an area of 500,000 square meters in lot area; the length of the quay would be 1200 meters. It was possible to anchor up to 6 large ships each with a displacement 10,000 ton. The construction of a hangar for airplanes, helicopters and large training facilities were also being planned. The total cost of construction was 3,340 million yuan (about 67,000 million yen), and the central government would pay for the expenses.
It seems that China is making the necessary long term preparations for its advance into the South China Sea.
