SEOUL, South Korea (AP) -- North Korea informed China it may drop its plan to test its first atomic bomb if the United States holds bilateral talks with the communist country, a former South Korean lawmaker said Sunday. The North also denied speculation that its nuclear test was imminent and said the regime has not raised the alert level of the country's military, said Jang Sung-min, citing a telephone conversation with an unidentified Chinese diplomatic official. North Korea warned the Chinese official, however, that it would accelerate its preparations for a nuclear test if the United States moves toward imposing sanctions or launching a military attack, Jang said, citing his contact.
