N Korea could consider change of approach if US maintains its sanctions: Kim

North Korea could consider a change of approach if the US maintains its sanctions on the nuclear-armed country, leader Kim Jong Un warned in his New Year speech Tuesday after 12 months of diplomatic rapprochement. "If the US does not keep its promise made in front of the whole world," Kim said, "we may be left with no choice but to consider a new way to safeguard our sovereignty and interests".
