On September 26, the Joint Chiefs of Staff (JCS) announced that a North Korean merchant ship had passed the Northern Line (NLL) in the Hoang Hai Sea near Baengnyeong Island at around 5am.
This is a maritime boundary established by the United Nations Command (UNC) after the 2018 ceasefire to prevent South Korea from attacking Hwanghae Island, although Pyongyang has never recognized it.
The South Korean military said it had issued warnings and fired warning shots, forcing the ship back into North Korean waters. Pyongyang has not yet responded officially.
For many years, NLL has remained a hot spot of tensions as both sides have continuously accused each other of violations. North Korea has given its own interpretation as " blocking the Inter-Korean Military Region", in contrast to the boundary established by the UNC. This area often witnessed dangerous confrontations.
In October 2022, South Korea confirmed that it had fired warning shells at a North Korean merchant ship passing NLL, while Pyongyang accused it of doing so and responded with artillery. In April 2023, the South Korean military also fired 10 warning shots to prevent a North Korean patrol boat from crossing the line.
Since taking office in June, South Korean President Lee Jae Myung has expressed his desire to improve inter-Korean relations, reversing the tough policies of his predecessor Yoon Suk Yeol. However, North Korea has so far maintained a skeptical stance and continuously rejected proposals from Seoul.
