SEOUL: Top US and South Korean officials agreed on Thursday to try to convince North Korea to return to talks on its nuclear program, which Pyongyang has insisted it won't do in protest of what it calls US hostility. US deputy secretary of State Wendy Sherman was in Seoul as part of her regional tour that will take her to China this weekend. She'll be the highest-ranking US official to visit China since President Joe Biden took office in January. On Thursday, she met South Korean foreign minister, Chung Eui-yong, for talks on North Korea, the military alliance between Seoul and Washington and other regional issues. The two decided to continue close consultations to get North Korea to return to talks and agreed dialogue is essential to the complete denuclearization and permanent peace on the Korean Peninsula, Chung's ministry said in a statement. Chung asked Sherman to strive to bolster the South Korean-US alliance. Sherman responded she would do so, saying the alliance is key to peace, security and prosperity in the Indo-Pacific region and Northeast Asia, according to the statement. US-led diplomacy aimed at stripping North Korea of its nuclear program in return for economic and political benefits remain stalled for about 2 ½ years. A major sticking point is North Korea's calls for the United States to abandon policy it considers hostile to it - an apparent reference to punishing US-led sanctions imposed over its past nuclear and missile tests. Last month, the influential sister of North Korean leader, Kim Jong Un, dismissed prospects for an early restart of the nuclear diplomacy, saying US expectations of talks would "plunge them into a greater disappointment." After her statement, Kim's foreign minister said North Korea wasn't even considering the possibility of any contact with the Americans that he said "which would get us nowhere, only taking up precious time." The blunt back-to-back statements cloud hopes for the diplomacy's resumption that flared after Kim said North Korea was ready for both dialogue and confrontation, though more for confrontation. Some experts say North Korea will likely find the urgent need to return to talks with the United States if its current pandemic-related economic difficulties further worsen.
