ABC News' Kirit Radia Reports: The State Department today confirmed that North Korea had informed various international agencies that it plans to launch "some sort of experimental communications satellite" during the first week of April. Acting spokesman Robert Wood warned that such a launch would be a "provocative" act that would destabilize the region. "We think the North needs to desist or not carry out this type of provocative act and sit down with the other members of the six-party talks and work on the process of denuclearization of the Korean Peninsula," Wood told reporters. Wood, however, conceded that the US did not know how to deter Pyongyang from going ahead with its launch plans. "It's hard to say what will influence North Korea. We just don't know. What we want to try to do is work with our partners and others around the world who share this interest in preventing the North from carrying out this type of provocative act," he said. Wood would not elaborate on Secretary of State Hillary Clinton's remarks yesterday that the US and its allies were weighing a range of responses should North Korea proceed with the launch. He said the US is engaged in diplomatic efforts to try and convince Pyongyang not to go ahead, but provided no further details. A senior State Department official later said that the US and North Korea had communicated last week via the so-called New York Channel, that is through their diplomatic missions at the United Nations, but did not know if this specific issue was discussed. Yesterday Secretary Clinton said US six-party talks envoy Stephen Bosworth was prepared to go to Pyongyang on his recent trip to Asia, but was not invited. "He was not invited to go to North Korea, which we regret," Clinton said yesterday after meeting with the visiting Chinese foreign minister. Today Wood said there were no plans to send Bosworth to North Korea.
