DPRK nuke tests threaten itself and others

The Democratic People's Republic of Korea announced on Wednesday that it had successfully tested its first hydrogen bomb. China Daily's Zhang Zhouxiang interviewed three experts to bring readers their views:

China has long insisted that its cooperation with the DPRK be based on the latter not conducting nuclear tests. What the DPRK claims to have done on Wednesday violates that principle and will damage Beijing-Pyongyang relations.

Worse, it means more trouble for China because the US might strengthen its military presence in the ROK. The US has been trying to deploy anti-ballistic missile defense systems in the ROK, and China has been persuading the latter not to agree to it. By claiming to have tested an H-bomb, the DPRK has offered the best excuse to the US to get the ROK's nod to do so.
