U.S. President Barack Obama's reelection campaign appears to be showing a lack of interest in continuing the six-way nuclear talks established to address North Korea’s nuclear ambitions.

Key figures devising foreign affairs and defense-related pledges for Obama as he seeks reelection have expressed no interest in the six-nation talks.

Obama’s key aides stressed during a recent meeting with South Korea’s Ambassador to Washington Choi Young-jin that they believe that a new negotiation framework is needed to tackle the North’s nuclear issue.

Such aides reportedly are interested in a comprehensive negotiation method to address security issues on the Korean Peninsula, including three-way or four-way talks proposed by former U.S. Special Representative for North Korea Policy Stephen Bosworth.

Republican presidential candidate Mitt Romney has expressed a negative position on the six-way nuclear talks. Romney said he plans to keep China in check if he becomes president, which would make it difficult for the U.S. to take part in the six-nation talks since China is taking a leading role in the dialogue.
