The United States does not expect an immediate response from the six-party talks for its proposal on dismantling the nuclear program of the Democratic People's Republic of Korea (DPRK), White House spokesman Scott McClellan said on Wednesday in Washington.

"We will be presenting this at the six-party talks and we do not expect an immediate response. We expect all parties will look at it. They will go back to their capitals and discuss it," McClellan said.

"There would be a process that would involve a short preparatory period where they would, as part of their effort to dismantle their nuclear program, disable all their nuclear weapons and weapons components, to begin with. And then that would be followed by the permanent and verifiable dismantlement of their nuclear program," McClellan said.

The United States will take steps to ease the "political and economic isolation" of the DPRK, McClellan said.

"What you would see would be some provisional or temporary proposals that would only lead to lasting benefit after North Korea dismantles its nuclear program," McClellan said.

The six-party talks are currently held in Beijing and US negotiators on Wednesday presented the first detailed proposal on resolving the standoff with the DPRK, offering energy aid and a security guarantee in exchange for dismantling its nuclear program.
