Beijing: US on August 29 assured it has no plans to attack North Korea as China, donning the robe of a mediator, said a six-point consensus including persistent efforts to bridge differences between Washington and Pyongyang has been reached at the six-nation talks on the Korean nuclear issue which ended without any major breakthrough.

"The US said that it had no intention to threaten North Korea, no intention to invade and attack North Korea, no intention to work for regime change in North Korea," China's Vice Foreign Minister Wang Yi told reporters after the talks.

He said both Washington and Pyongyang submitted their demands and wishes at the talks while all other nations explained their proposals and positions.

While the envoys reached consensus on the need to address Pyongyang's security concerns and agreed that more talks were necessary, they failed to set a time-table.

Terming the talks as a "failure", Russia blamed the obstinate and unbending stands of Pyongyang and Washington for the talks ending without any substantial achievement.

Russian Deputy Foreign Minister Alexander Losyukov, who represented his country at the talks, said he had held separate parleys with the US and North Korean leaders in a last ditch attempt to broker a deal between the two.

He denied that North Korea threatened to strengthen its nuclear arsenal at the talks and that it resulted in discussions ending in acrimony.

As the talks wound up in Beijing, a statement carried by North's official KCNA agency threatened to strengthen its nuclear arsenal unless Washington met its demands for a resolution of the nuclear crisis.
