North Korea escalates tensions as Chinese personnel were recently spotted on a disputed offshore structure, highlighting that maritime tension escalates between Seoul and Beijing. Moreover, the development marks the first confirmed human presence on the Sunlan No. 2 installation in the Provisional Measures Zone.
The revelation came from Rep. Yi Byeong-jin of South Korea’s Democratic Party. Specifically, he presented photographs showing five individuals on the structure, including one in a diving suit maintaining oxygen tanks near the waterline. Additionally, two people appeared on the upper deck, and two more were on the mid-left section of the platform.
The Sunlan No. 2 structure was built by China last year within the overlapping exclusive economic zones of South Korea and China. Consequently, analysts warn that the move reflects Beijing’s ongoing use of “gray zone” tactics in contested maritime areas.
The West Sea’s Provisional Measures Zone, which includes the submerged reef Ieodo or Socotra Rock, has long been a flashpoint. The area lies 149 kilometers southwest of Mara Island, Korea’s southernmost point. Therefore, Chinese activity in the PMZ has intensified, prompting South Korea and international observers to monitor developments closely.
In response, Seoul is considering countermeasures to safeguard its maritime sovereignty. Accordingly, lawmakers and Coast Guard officials are holding audits and planning strategic surveillance enhancements. Furthermore, the United States has reportedly approached a Korean research group to fund the installation of a powerful maritime radar in the contested waters.
Experts say maritime tension escalates due to Beijing’s strategic approach combining civilian and paramilitary presence on disputed structures. “China is increasing its foothold in contested waters while avoiding direct confrontation,” said one defense analyst.
South Korean officials stress the importance of balancing diplomacy with deterrence. Thus, strengthened maritime monitoring, combined with international cooperation, aims to reduce the risk of miscalculations or conflict escalation.
As the situation develops, maritime tension escalates underscore the growing complexity of regional security in East Asia. Consequently, Seoul will need to carefully manage both domestic pressure and international relations to ensure stability.
The West Sea dispute remains a critical test for South Korea’s maritime strategy, requiring constant vigilance and strategic investment in surveillance and response capabilities.
