President Trump has made the decision to withdraw from the scheduled June 12th summit with North Korean Chairman Kim Jong-un. [Copy of letter below]
Ultimately the decision to withdraw is an outcome of changes in posture initiated strategically by China and Chairman Xi Jinping. China hoping to leverage a U.S. trade outcome by playing the strings on DPRK Chairman Kim Jong-un.
The timing of the meetings between China and DPRK, mirrors the changes in posture by the DPRK and reflects a transparency. Communist Beijing is engaging with the Trump administration in traditional dragon-mode their zero-sum outlook. In response, President Trump drops the Panda approach and confronts the manipulation directly.
Likely President Trump will immediately increase sanction enforcement and reposition again for a pending naval blockade.
