SEOUL, March 18 (AP) - North Korea said on Thursday (Mar 18) it will ignore a US offer for talks unless it withdraws its hostile policy, after Washington reached out to Pyongyang in a bid to resume nuclear negotiations.

The statement by Choe Son Hui, the first vice foreign minister, came hours before the US and South Korean foreign and defense chiefs met in Seoul for their first joint talks in five years to discuss North Korea’s nuclear program.

“What has been heard from the US since the emergence of the new regime is only a lunatic theory of ‘threat from North Korea’ and groundless rhetoric about ‘complete denuclearisation,’” Choe said, calling the offer for talks a “time-delaying trick”.

“We have already declared our stand that no (North Korea)-US contact and dialogue of any kind can be possible unless the US rolls back its hostile policy toward (North Korea). Therefore, we will disregard such an attempt of the US in the future, too.”

US-led diplomacy focusing on North Korea’s nuclear weapons remains stalemated for about two years because of disputes over US-led sanctions.

Experts are debating whether the United States and its allies should settle for a deal that would freeze North Korea’s nuclear activities in return for relaxing sanctions to prevent its arsenal from growing.

Earlier this week, the powerful sister of North Korean leader Kim Jong Un threatened to abandon rapprochement with South Korea and warned the United States to “refrain from causing a stink,” while criticising regular US-South Korean military drills that her government views as an invasion rehearsal.

Choe again took issue with this month’s drills, saying that the United States “openly started aggression-minded joint military exercises targeting us”.

Some experts say North Korea, which is eager to win sanctions relief, may further raise animosities with missile tests to boost its leverage in any negotiations with the United States. North Korea’s moribund economy is under additional pressure because of the pandemic-related border closure that has significantly shrunk its external trade and a spate of natural disasters last summer.

US Secretary of State Antony Blinken said during a visit to Tokyo earlier this week that Washington had reached out to North Korea through several channels, including in New York, starting in mid-February, but it has not received any response.

He said the Biden administration was looking forward to completing its policy review on North Korea in coming weeks and was looking both at possible “additional pressure measures” and “diplomatic paths”.

When Blinken met South Korean Foreign Minister Chung Eui-yong on Wednesday, he said the United States will work with allies to achieve the denuclearisation of North Korea and criticised what he called North Korea’s “systematic and widespread abuses against its own people”.

According to the State Department, Blinken and Chung also reaffirmed a shared commitment to address North Korean nuclear and ballistic missile issues that they said are “a priority for the alliance”.

Choe said US attempts to contact North Korea included emails and telephone messages via various channels.

She said that even on the eve of its drills with South Korea, Washington sent a message “imploring us to respond to its request through a third country”.

Choe said it will “only be a waste of time to sit with the US”.
