This video shows recent events in China and how they differ from how China represents itself. I’ve read news reports of studies showing how China leads the west in this or that. This video shows how the current Chinese culture trades quality with the appearance of quality. Until this changes, China will not follow Japan as a high quality provider of technological goods. Does this mean that China does not possess some cutting age technology, no. It does mean that there is some question as to if their PL-15 long range air to air missile works as claimed. In fact this is true of much of their claimed technological advances.
The two men presenting this video lived in China for decades. The video was recorded two days ago.
