BBC NEWS | Asia-Pacific | China gets tough with North Korea
So it appears that even China is becoming truly fed-up with it's crazy neighbor. Thoughts?"The Chinese used to think that Kim Jong-il was just playing nuclear poker with the Americans, South Korea and Japan," he said.
"But now they think he really does want a nuclear arsenal."
Mr Lam believes Mr Kim is trying to develop these weapons to secure the succession of his third son, Kim Jong-un.
China's position towards North Korea noticeably changed after the North carried out a nuclear test at the end of May.
This seemed to end any hope that the six-party talks - aimed at stopping North Korea's nuclear programmes - would succeed.
Not only did this make the region more volatile, it was also embarrassing for China.
