South Korean President Park Geun-Hye called on Tuesday for "courage" in standing up to North Korea, saying a fundamentally new approach was needed to derail Pyongyang's nuclear weapons programme.<br />As the North's neighbour and prime target, South Korea must take a leading role in sanctioning Pyongyang for its nuclear provocations, Park said in an address to the National Assembly.<br />The speech came a week after Park took the unprecedented step of shutting down operations at the jointly run Kaesong industrial estate in North Korea, triggering an aggressive response from Pyongyang.<br />"It has become clear that we cannot break North Korea's will to develop nuclear weapons through existing means and goodwill," Park said.
