I don&#x27;t think China has anything to gain by giving NK advanced rocket technology.  China already have enough power to impress its neighbors and is not afraid to show it off, so there&#x27;s no need to prop up a satellite nation which is barely controllable.<p>If anything, NK rockets are a very handy excuse for Japan to re-arm itself (or continue arming itself, depending on how you look at it), and I can&#x27;t imagine China liking its prospect.  Meanwhile, South Korean government is already discussing plans to introduce THAAD (whatever that is) into SK, and apparently China is pretty upset about that, too.  Sigh.
