Washington: Former New Mexico governor Bill Richardson and Google chairman Eric Schmidt will head to North Korea next week on a "private humanitarian mission," Richardson's office said.
Richardson, a veteran troubleshooter on North Korea, will hold a press conference at the airport in Beijing on Thursday, his office said in a statement, adding that no journalists would be accompanying the delegation.
The US State Department has voiced concerns about the trip, saying it was ill-timed in the wake of Pyongyang's widely condemned rocket launch last month.
Richardson has said the trip is linked to North Korea's arrest late last year and planned prosecution of a US citizen of Korean descent.
The former US ambassador to the United Nations has been to North Korea a number of times in the past 20 years and has been involved in negotiating the release of US citizens detained in the isolated state.
Accompanying the pair will be Richardson's longtime aide on North Korea, K A "Tony" Namkung, Jared Cohen, director of Google Ideas, a think tank run by the California-based Internet giant, and some staff, the statement said.
Spokespeople for both Richardson and Schmidt did not immediately respond to requests from AFP for further details about the trip.
Richardson said Friday he hoped the trip would be "positive", and dismissed US concerns about the mission, saying it had already been postponed once at Washington's request and that the State Department should not be "nervous."
He stressed he and Schmidt would be traveling as private citizens, representing neither the US government nor Google.
"We will make an assessment and see what comes of our visit. I think it will be positive," Richardson told CNN.
"We're not representing the State Department, so they shouldn't be that nervous," he said in an earlier interview with CBS.
The son of Kenneth Bae, the detained American, contacted Richardson and asked for his assistance, the former governor said.
The US citizen, who was arrested in November, entered the country as a tourist according to North Korea's official Korean Central News Agency (KCNA), which said he had admitted committing a crime against the state.
