South Korea and the United States expressed a united front against North Korea's nuclear test and support of U.N. sanctions, but there were no signs that Seoul would take any immediate steps to come into line with Washington's hard-line approach to dealing with Pyongyang. U.S. Secretary of State Condoleezza Rice said she didn't mean to pressure the South to take any specific steps, speaking at a joint news conference with South Korean Foreign Minister Ban Ki-moon. However, she added, «Everyone should take stock of the leverage we have to get North Korea to return to the six-party talks» _ referring to international arms talks that have been on hold since last year, the Associated Press reported.
