The State Department says it has made no decision yet on North Korea's U.S. visa request for its chief negotiator at stalled nuclear disarmament talks.

Spokesman P.J. Crowley told reporters Wednesday that the United States is aware of Kim Kye Gwan's request about getting a visa to make a private visit.

He says there has been a discussion about the inquiry but no decision about granting a visa.

South Korean media has cited an unidentified source in Beijing in reporting that Kim wants to attend a seminar in San Francisco before heading to New York to meet with Washington's lead nuclear negotiator Sung Kim.

North Korea quit six-nation nuclear talks and conducted a second nuclear test last year, drawing tightened U.N. sanctions.
