SEOUL, South Korea (AP) — The powerful sister of North Korean leaderKim Jong Unsaid her country will never see South Korea as a partner for diplomacy, state media reported Wednesday inher latest taunt of Seoul'snew efforts to mend ties. Kim Yo Jong, who is one of her brother's top foreign policy officials, denounced the ongoing South Korea-U.S. military drills as a "reckless" invasion rehearsal and claimed Seoul's peace gestures conceal a "sinister intention" to blame Pyongyang for strained relations. Her comments came during a meeting Tuesday with Foreign Ministry officials about her brother's diplomatic strategies, the North's official Korean Central News Agency said. She urged the Foreign Ministry to pursue "proper countermeasures" against South Korea, which she labeled the "most hostile state," as well as Seoul's allies. On Monday, Kim Jong Un condemned the South Korean-U.S. military drills and vowed a rapid expansion of his nuclear forces as he inspected hismost advanced warship being fitted with nuclear-capable systems. KCNA said Kim Yo Jong condemned the South as the "top-class faithful dog" of the United States and that the reparation of inter-Korean relations desired by Seoul "will never" happen. The siblings' back-to-back statements followed the latest outreach by South Korean President Lee Jae Myung, who said last week that Seoul wouldseek to restore a 2018 inter-Korean military agreementaimed at reducing border tensions, while urging Pyongyang to reciprocate by rebuilding trust and resuming dialogue. In response to Kim Yo Jong's latest comments, South Korea's Unification Ministry, which handles inter-Korean affairs, said Lee's government will continue to take "proactive steps for peace" and called for mutual respect between the countries. Since taking office in June, Lee has moved to repair relations that worsened under his conservative predecessor's hard-line policies, including removing front-line speakers that broadcast anti-North Korean propaganda and K-pop. In a nationally televised speech Friday, Lee said his government respects North Korea's current system and that the wealthier South "will not pursue any form of unification by absorption and has no intention of engaging in hostile acts." But he also stressed that the South remains committed to an international push to denuclearize the North and urged Pyongyang to resume dialogue with Washington and Seoul. Angered by expanding South Korean-U.S. military drills, Kim Jong Un last year declared thatNorth Korea was abandoning long-standing goals of a peaceful unification with South Koreaand rewrote the North's constitution to mark the South as a permanent enemy. Kim Yo Jong has repeatedly dismissed calls to revive negotiations aimed at winding down the North's nuclear and missile programs, which derailed in 2019 following her brother's collapsed summit with U.S. PresidentDonald Trumpduring his first term. SinceRussia's invasion of Ukraine, Kim Jong Un has made Moscow the priority of his foreign policy, sending it troops and weapons while using the Russia-Ukraine war as a distraction to accelerate his military nuclear program. In her meeting Tuesday, Kim Yo Jong suggested that Pyongyang seeks to compete with Seoul diplomatically, claiming the South "will not even have a subordinate role in the regional diplomatic arena," which she claimed will be centered on the North.
