A delegation of senior North Korean officials is in South Korea to pay their respects to the late former President Kim Dae-jung, who worked to reunite the two sides. They will leave before Sunday’s funeral, however, so as not to mix with the present government, whose hardline policies toward the North have rubbed Pyongyang the wrong way.A spokesman for South Korea’s Unification Ministry said: “Until now, North Korea’s unilateral measures have caused non-government economic cooperation to contract. In practical terms this retrograded the South-North relationship. This should never happen again. We are going to strengthen the system of provisions between South and North, and thoroughly execute these measures.” North Korea has just lifted restrictions on South Koreans’ crossing the border. The destitute North’s communist regime has made a series of rare conciliatory moves this month. It was hit with Chinese-backed UN sanctions for its nuclear test in May that drove it further into isolation and hurt its already broken economy.
