OPLAN 5029 is a proposed military operation plan by the United States and South Korea for dealing with "sudden change" in North Korea,[1][2][3] such as a coup d'état, revolution, large scale defections, outflow of weapons of mass destruction, hostage situations involving South Koreans, or major natural disasters.
The DPRK's Korean Central News Agency responded by claiming that "the U.S. and the South Korean war-like forces [had] openly held an anti-DPRK military confab at which they agreed to 'rapidly dispatch reinforcements in contingency'" and claimed "U.S. belligerent forces would be well advised not to misjudge the army of Songun and the will of the DPRK but stop their reckless moves for a new war."
One report written by the United States Institute of Peace and the Center for Strategic and International Studies suggested a strong preference for authorization and coordination under a UN mandate, but a willingness to act unilaterally in restoring order to the event of a sudden collapse (including the deployment of soldiers and other personnel for humanitarian, peacekeeping, and nonproliferation purposes).
[citation needed] In the trial of former South Korean spy Park Chae-seo, Park claimed knowledge of a contingency plan named "the Chick Plan" from a director-level Chinese intelligence official (its name referring to a large mothering hen protecting the small eggs beneath her).
Park also claimed that no Chinese investment in North Korea had been allowed past this line and that PLA soldiers had been stationed in Shenyang, with operational roads built over the Yalu and Tumen Rivers at the cost of KRW2.5 trillion.
