Analysis - North Korea's Kim Jong-un to ride out sanctions in nuclear push

SEOUL (Reuters) - Fresh U.N. sanctions are unlikely to halt North Korea's nuclear programme given that seven years of previous measures from the world body and more than 50 years of U.S. penalties have failed to dissuade North Korea from trying to develop banned weapons.

Under new leader Kim Jong-un, the North has pursued its nuclear programme even more aggressively, experts in Seoul said. The 30-year old Kim, in power for just over a year, also seems more willing to shun China, his sole powerful backer, than his father Kim Jong-il was, one of the experts said.
