Tension has been building in the South China Sea over the last couple of weeks due to questions on who owns it. This part of the sea, brings in 5 trillion dollars of trade goods a year, causing it to be very important to China and any country who gains the money from these trades. Just recently, a Japanese submarine was seen approaching the Philippines. This has made for an increase in tension, but the commander of the Japanese submarine assures that this is just a training exercise. Although it may very well be a training exercise, a Japanese submarine or ship has not been seen in that area for over 10 years, causing many to question. In order to grasp how large of an issue this is, China, the Philippines, Japan, Taiwan, and Vietnam are all disputing over which has the authority to claim the sea and islands associated with this area. These countries have all been refusing to back down and don’t show any signs of progress in the near future. As of now, all is calm, but this tension seems to only be building over the last couple of weeks and will continue to get worse.
