大约18个月前，韩国开始用边境扩音器向朝鲜播放K-pop和新闻，朝鲜随即用动物叫声和怪异口哨回击；今年早些时候边境转为寂静，背景是李在明于6月就任总统并迅速推动静音。此举逆转了前任尹锡悦（2022—2024年在任）的升温路线：尹在去年重新开启自2018年以来未再使用的扩音器。
李在明还让越境散发传单的行动大多停止；更具争议的是，韩国情报机构今年首次自2010年以来暂停对朝广播电台，时间点紧随美国由政府资助、同样对朝播出的新闻服务被拆解之后。据美国智库史汀生中心估算，自5月以来进入朝鲜的境外节目时长已下降约80%，仅剩少量由活动人士运营的短波电台从台湾、菲律宾、乌兹别克斯坦等地发射。
在朝鲜将不受审查的信息视为重大威胁、惩罚升级到长期监禁且有时甚至处决的情况下，活动人士正转向更迂回的触达方式，包括一个面向半岛外朝鲜人（如留学生或劳工）的网络电台，寄望听众把内容转述给国内亲友。尽管朝鲜无法自由上网，李在明仍称广播陈旧且浪费，并以这些“小让步”试图防止局势恶化；同时外界预期唐纳德·特朗普可能在明年与金正恩举行第二次面对面会晤。
About 18 months ago South Korea began blasting K-pop and news into North Korea from border loudspeakers, and the North replied with animal cries and eerie whistles; earlier this year the frontier fell silent as Lee Jae Myung took office in June and quickly moved to mute them. The shift reverses the escalation under his predecessor Yoon Suk Yeol (in office 2022–2024), who switched the speakers back on last year after they had not been used since 2018.
Lee also largely halted cross-border leaflet launches, and more controversially South Korea’s spy agency suspended radio broadcasts into the North this year for the first time since 2010, shortly after America’s state-funded services that also broadcast into North Korea were dismantled. The Stimson Center estimates the total hours of outside programming entering the country have fallen by roughly 80% since May, leaving only a small set of activist-run shortwave outlets transmitting from places such as Taiwan, the Philippines, and Uzbekistan.
With the regime treating uncensored information as a major threat and tightening penalties to lengthy prison terms and sometimes execution, activists are pivoting to indirect channels, including an internet-based station aimed at North Koreans overseas (students or laborers) who might relay content back home. Despite North Koreans lacking free internet access, Lee has called radio antiquated and wasteful and is betting these “small things” can prevent further worsening as expectations grow that Donald Trump may meet Kim Jong Un in person for a second time next year.
