The United States yesterday announced new sanctions against North Korea, targeted against its leadership, and warned of serious consequences if it again attacked the South.


Relations across the divided peninsula have turned increasingly hostile after South Korea accused the North of sinking one of its warships in March.


Secretary of State Hillary Clinton said Washington was ready to return to international talks over North Korea’s nuclear weapons program if Pyongyang sent a “positive signal,” but that there had been none so far.


The sanctions aim to prevent North Korea from selling arms and procuring luxury goods, as well as to stop entities operating illicitly overseas.
