US envoy for DPRK policy Stephen Bosworth told reporters outside the US Mission to the United Nations that the talks were "constructive and business-like."

"As the United States said from the beginning, these discussions were to explore the willingness of the DPRK to take concrete and irreversible steps toward denuclearization. In that regard, these were constructive and business-like discussions," Bosworth said.

"The United States reiterated that the path is open to the DPRK towards the resumption of talks, improved relations with the United States, and greater regional stability if the DPRK demonstrates through actions that it supports the resumption of the Six-Party process as a committed and constructive partner," he said.

He added that before deciding on next steps to resume the process, the United States "will consult closely with" the Republic of Korea (RoK) and other partners in the six-party talks.

DPRK Vice Foreign Minister Kim Kye Gwan left the residence of the US Mission to the UN earlier July 29 afternoon, shortly after a working lunch with their US counterparts.

He said that the meeting was over and there was no joint statement.

Kim, speaking in Korean, said that the dialogue was "constructive and business-like." The two sides conducted "comprehensive" talks on issues of mutual interests, and the DPRK "would continue to have meetings with the United States," he said.

The bilateral talks came after US Secretary of State Hillary Clinton on July 24 invited Kim to New York for talks on the potential resumption of the six-party talks, which has been on hold for more than two years.

The talks between Bosworth and Kim were the first top level contacts between the two countries since Bosworth went to Pyongyang in December 2009.

On July 22, the RoK's chief nuclear envoy Wi Sung-lac and his DPRK counterpart Ri Yong-ho held a bilateral meeting in Bali, Indonesia, during which, the two sides agreed to work to resume the six-party talks.

The six-party talks, involving China, the DPRK, the United States, the RoK, Russia and Japan, began in 2003. Six rounds of talks were held before stalling in December 2008.
