"What's China doing..?" Apparently adhering to 60 year-old anti-imperialist dogma. This outcome isn't good for anyone. But it's disadvantageous to China more than anyone; missile defence system in S Korea, hitherto unthinkable talk of Japanese nukes, and if the worst does happen and it comes to nuclear war, it's on China's doorstep. A thoroughly inept and unstatesmanlike performance!
