The United State says there seems to be no change in North Korea's power succession.

White House Press Secretary Jay Carney told reporters on Wednesday that North Korean leader Kim Jong-il designated Jong-un as his official successor before his death, and at this time Washington sees no indication that that has changed.

Carney made the remark after being asked to comment on reports that there were some signs indicating a move for a power-sharing agreement within the North's inner circle.

He said the U.S. is monitoring events in the communist state closely. He added the U.S. hopes the new leadership in the North will take steps that will ensure a better future for its people, and abide by its commitments to denuclearize.

Since the death of Kim Jong-il, Washington has consistently used the term “North Korea’s new leadership.” Wednesday marked the first time for Washington to actually mention Kim Jong-un as the new leader of the reclusive state.
