China has floated a red line in the South China Sea claiming 79%

by

China has floated a barrier about 150 miles west of Luzon, the main island of the Philippines and 560 miles from China owned land.

China is claiming 79% of the South China Sea and blocking fisherman from those waters today. This is a way bigger issue than fishing in the long run.
