The visit comes on the heels of North Korea’s latest missile launches At the DMZ, Harris went to the top of a ridge, near guard towers and security cameras PANMUNJOM, Korea: US Vice President Kamala Harris capped her four-day trip to Asia with a stop Thursday at the Demilitarized Zone dividing the Korean Peninsula as she emphasized US commitment to the security of its Asian allies in the face of an increasingly aggressive North Korea. The visit comes on the heels of North Korea’s latest missile launches and amid fears that the country may conduct a nuclear test. Visiting the DMZ has become something of a ritual for American leaders hoping to show their resolve to stand firm against aggression. North Korea fired two short-range ballistic missiles on Wednesday, while Harris was in Japan, and had fired one before she left Washington on Sunday. The launches contribute to a record level of missile testing this year that is intended to move Pyongyang closer to being acknowledged as a full-fledged nuclear power. At the DMZ, Harris went to the top of a ridge, near guard towers and security cameras. She looked through bulky binoculars as a South Korean colonel pointed out military installations on the southern side. Then an American colonel pointed out some of the defenses along the military demarcation line, including fence topped with barbed wire and claymore mines. He said American soldiers regularly walk patrols along a path. “It’s so close,” Harris said. Her tour visit to the observation post came after she met US service members and some of their relatives at the Camp Bonifas Dining Facility, where she said she wanted them to know “how grateful and thankful we are.” “I know it’s not always easy. Most of the time it’s not,” she said. She asked a soldier from Florida on whether he checked in on his family after Hurricane Ian. “Yeah, they’re up on a hill,” he said. When another soldier stammered nervously while introducing himself, Harris said, “You know your name!” “They’re going to give you such a hard time when this is over,” she joked. Earlier, Harris met with South Korean President Yoon Suk Yeol at his office in Seoul where they condemned North Korea’s intensifying weapons tests and reaffirmed the US commitment to defend the South with a full range of its military capabilities in the event of war, Yoon’s office said. They expressed concern over North Korea’s threats of nuclear conflict and pledged an unspecified stronger response to major North Korean provocations, including a nuclear test, which South Korean officials say could possibly take place in coming months. Harris and Yoon were also expected to discuss expanding economic and technology partnerships and repairing recently strained ties between Seoul and Tokyo to strengthen their trilateral cooperation with Washington in the region. Harris’ trip was organized so she could attend the state funeral of former Japanese Prime Minister Shinzo Abe, but her itinerary was dominated by security concerns, a reflection of fears about China’s growing power and North Korea’s ramped-up testing activity. In every meeting, Harris tried to lay to rest any fears that the United States was wavering in its commitment to protect its allies, describing American partnerships with South Korea and Japan as the “linchpin” and “cornerstone” of its defense strategy in Asia. Yoon, who took office earlier this year, had anchored his election campaign with vows to deepen Seoul’s economic and security partnership with Washington to navigate challenges posed by the North Korean threat and address potential supply chain risks caused by the pandemic, the US-China rivalry and Russia’s war on Ukraine. But the alliance has been marked by tension recently. South Koreans have expressed a sense of betrayal over a new law signed by President Joe Biden that prevents electric cars built outside of North America from being eligible for US government subsidies, undermining the competitiveness of automakers like Seoul-based Hyundai. There are indications North Korea may up its weapons demonstrations soon as it refines its missiles and delivery systems and attempts to pressure Washington to accept the North as a nuclear power. South Korean officials said last week that they detected signs North Korea was preparing to test a ballistic missile system designed to be fired from submarines. The US aircraft carrier USS Ronald Reagan was to train with South Korean and Japanese warships in waters near the Korean Peninsula on Friday in the countries’ first trilateral anti-submarine exercises since 2017 to counter North Korean submarine threats, South Korea’s navy said Thursday. US and South Korean officials also say North Korea is possibly gearing up for its first nuclear test since 2017. That test could come after China holds its Communist Party convention the week of Oct. 16, but before the United States holds its midterm elections Nov. 8, according to South Korean lawmakers who attended a closed-door briefing from the National Intelligence Service.
