On March 23, 2008, North Korea test-launched a barrage of short-range missiles. "That move was prompted by the North's anger over South Korean statements that any expansion of the [joint industrial zone] project in the border city of Kaesong would only happen if the North resolved the international standoff over its nuclear weapons," the reported.
The test fire was also seen as a response to the South Korean government's firm stance on relations with Pyongyang, with the South's newly instated conservative president, Lee Myung-bak, ending a decade of "Sunshine policy" engagement with the North.
