Thousands attended the rally in Seoul
Newspapers in China, Japan and South Korea ponder the way ahead as diplomats at the UN discuss possible sanctions against North Korea after its claim to have carried out a nuclear test.
One Chinese daily argues that "blindly adopting force" will not work, while a Japanese paper notes that Tokyo's call for sanctions won "a ringing endorsement from Washington".
South Korean papers agree that Seoul's current policy of engagement and dialogue with North Korea cannot continue.

The future of the North Korean issue still needs to be resolved within the framework of the six-party talks, and blindly adopting force will not work... If China continues to provide aid to North Korea in the future, this is not a show of support for North Korea's nuclear test, but is for the sake of the North Korean people.

"Hawkish" US and Japanese politicians hope to use fuller sanctions to spur the downfall of the current North Korean government, but in the long run sanctions may not effectively address the North Korean nuclear issue and may indeed have the reverse effect.
JAPAN'S ASAHI SHIMBUN
Tokyo moved with uncharacteristic swiftness in pushing for sanctions against North Korea over its purported nuclear test on Monday, and in the process won a ringing endorsement from Washington for its actions.

The gap in the national interests of each country remains uncoordinated. The United States is still dreaming of "regime change"... China basically goes for "maintenance of the regime"... The answer is to rebuild cooperation among Japan, the United States and South Korea to consolidate a common strategic goal. The realistic goal is not "regime change" but "prevention of nuclear armament".

After the test, President Roh conceded that South Korea cannot continue the existing engagement policy and demonstrated his willingness to seek consultation with the international community in a more active way... Japan is clearly gaining momentum in persuading China and South Korea to move closer to its harder stance.
SOUTH KOREA'S CHOSON ILBO
The question is what role "dialogue" has played in resolving the North Korean nuclear standoff over the past three years? Insisting - in these hard times - on a formula that so signally failed when it was easier is tantamount to giving up on a resolution of the nuclear standoff altogether... Koreans and the world are fed up with this administration's hypocrisy. It might as well say frankly that there is nothing wrong with a nuclear-armed North Korea because the bombs will be ours once unification comes.
