North Korea may postpone the controversial launch of a long-range rocket that had been slated for liftoff as early as this week, state media said Sunday, as international pressure on Pyongyang to cancel the provocative move intensified.
Scientists have been pushing forward with final preparations for the launch from a west coast site, slated to take place as early as Monday, but are considering "readjusting" the timing, an unidentified spokesman for the Korean Committee for Space Technology told North Korea's state-run Korean Central News Agency.
It was unclear whether diplomatic intervention or technical glitches were behind the delay. A brief KCNA dispatch said scientists and technicians were discussing whether to set new launch dates but did not elaborate.
Word of a possible delay comes just days after satellite photos indicated that snow may have slowed launch preparations, and as officials in Washington, Seoul, Tokyo, Moscow and elsewhere urged North Korea to cancel a liftoff widely seen as a violation of bans against missile activity.
Commercial satellite imagery taken by GeoEye on Dec. 4 and shared Friday with The Associated Press by the 38 North and North Korea Tech websites showed the Sohae site northwest of Pyongyang covered with snow. The road from the main assembly building to the launch pad showed no fresh tracks, indicating that the snowfall may have stalled the preparations.
However, analysts believed rocket preparations would have been completed on time for liftoff as early as Monday.
In Seoul, officials at the Defense Ministry, Joint Chiefs of Staff and the Foreign Ministry said Sunday they were looking into what might be behind the possible delay.
North Korea announced earlier this month that it would launch a three-stage rocket mounted with a satellite from its Sohae station southeast of Sinuiju sometime between Dec. 10 and Dec. 22. Pyongyang calls it a peaceful bid to send an observational satellite into space, its second attempt this year.
The launch announcement captured global headlines because of its timing: South Korea and Japan hold key elections this month, President Barack Obama begins his second term next month and China has just formed a new leadership.
The United States, Japan, South Korea and others have urged North Korea to refrain from carrying out the launch, calling it a violation of U.N. Security Council resolutions on nuclear activity because the rocket shares the same technology used for firing a long-range missile.
China, the North's main ally and aid provider, noted its "concern." It acknowledged North Korea's right to develop its space program but said that had to be harmonized with restrictions including those set by the U.N. Security Council.
Past launches have earned North Korea international condemnation and a host of sanctions.
South Korean analysts said North Korea's announcement of a possible delay suggests the country wants to resume talks with the U.S. on receiving much-needed aid, or has yielded to diplomatic pressure by China.
North Korea may not fire the rocket if the U.S. actively engages in talks with Pyongyang and promises to ship stalled food assistance to the country, said Koh Yu-hwan, a professor of North Korean studies at Seoul's Dongguk University.
In February, the U.S. agreed to provide 240,000 metric tons of food aid to North Korea in exchange for a freeze in nuclear and missile activities. The deal collapsed after North Korea launched a long-range rocket in April.
Analyst Baek Seung-joo of the South Korean state-run Korea Institute for Defense Analyses in Seoul said China must have sent a "very strong" message calling for the North to cancel the launch plans.
"North Korea won't say it would delay the launch due to foreign pressure so that's why they say scientists and technicians are considering delaying it," he said.
The unexpected launch announcement was issued Dec. 1 as North Koreans began mourning late leader Kim Jong Il, who died on Dec. 17, 2011.
An April launch from the same new launch pad was held on April 13, two days before the centennial of the birth of his father, North Korea founder Kim Il Sung. That rocket broke up just seconds after liftoff.
The U.S. and other nations see the launches as covers for illicit tests of missile technology. North Korea has unveiled missiles designed to target U.S. soil, and has tested two atomic bombs in recent years, but has not shown yet that it has mastered the technology for mounting a nuclear warhead to a long-range missile.
Six-nation negotiations to offer North Korea much-needed aid in exchange for nuclear disarmament have been stalled since 2009.
