North Korean purge a reminder of China's progress since Cultural Revolution
Zhou Zunyou says China's reforms have led to significant steps in applying rule of law

Kim Jong-un's uncle by marriage and the former No 2 man in North Korea, Jang Song-thaek, was executed this month for his "anti-party and counter-revolutionary crime" or, in other words, plotting to overthrow the supreme leader, Kim.
He was also charged with a long list of other offences ranging from corruption to womanising, from gambling to distributing pornography, from drug use to half-hearted applause for young Kim's promotion. In a viciously worded report, North Korea's state media denounced him as a "traitor for all ages", "despicable human scum" and "worse than a dog".
When commenting on the killing of Jang, China's foreign ministry spokesman Hong Lei said it was the "internal affairs" of North Korea.
