In this video we analyze how RoRo ferries are essentially China’s secret weapon in supporting a possible invasion of Taiwan and we will try to answer two major questions: What are the sea-lift and amphibious capabilities of these vessels? How could China benefit by blurring the line of what is a war ship and what is a civilian ship?
