The Lianyungang branch of China’s Maritime Safety Administration announced no-sail zones in three designated areas of the West Sea, banning all ships from entering the port with navigational warnings due to “military training” purposes. With this established zone, South Korea’s Ministry of Foreign Affairs has raised concerns over the possibility of Beijing’s attempt to “militarize” the Yellow Sea, located between China and the Republic of Korea. 

Tensions rose between the two nations on April 17th following satellite imagery that revealed a steel rig installed by China in the Provisional Measures Zone (P.M.Z.)—where South Korea and China’s exclusive economic zones overlap. Additionally, according to Newsweek, a Pentagon report involving the People’s Republic of China highlighted the strength of the Chinese military—which has the largest naval force in the world—stating that the navy “conducted a robust level of global engagements.” This report, coupled with the latest development in South Korean relations, alludes to the possibility that China is aiming to expand its navy reach by pressuring the government of South Korea. 

In a maritime dialogue between South Korean and Chinese officials, China’s statement has been that the steel rig was simply a fish-farming facility with no placement pertaining to territorial rights. However, South Korea’s Director-General for Northeast Asian Affairs Kang Young-shin demanded that its “legitimate maritime rights should not be violated,” and has stressed for China to relocate their structures outside the P.M.Z. The Korean Minister of Oceans and Fisheries Kang Do-hyung has stated that the government was preparing “proportional response measures . . . with utmost seriousness from the standpoint of protecting maritime territory,” referencing the possibility of countering their “fishing farm” with the development of similar infrastructure in the Yellow Sea. 

 It is daring of China to instate a “no-sail zone” on contested waters without clear reason to South Korea; it is a fair assumption on the Ministry’s part to believe that China would take advantage of the current domestic issues in South Korea after former President Yoon Suk Yeol’s impeachment. Additionally, there is a close similarity of China’s rising territorial pressures against South Korea to the 2014 China–Vietnam oil rig crisis, in which tensions sparked as the China National Offshore Oil Corporation moved an oil rig to the disputed waters of the Paracel Islands where a Vietnamese fishing boat was sunk, and drove up anti-China sentiment in Vietnam with protests and riots. During which, China withdrew from the territory two months earlier than dated, potentially due to Vietnamese pressure, or because of their confirmation and discovery of a large, shallow gas field in the waters southwest of Hainan, coincidentally where the claimed waters of Vietnam and Taiwan lay. 

Additionally, North Korea, an ally of China, has recently advanced their nuclear arsenal—declaring itself as a “responsible nuclear weapons state” in 2022 despite sanctions that have been instated by the United States since 2006. Though, U.S. President Donald Trump has expressed support toward North Korea’s Kim Jong Un, referring to him as a “nuclear power” with whom he has a “great relationship” in an Oval Office meeting. Moreover, the Trump Administration had severed funds to news services like Radio Free Asia and Voice of America, which had been broadcasting nightly to North Korea, according to BBC, leaving the citizens of South Korea doubtful of U.S. assistance and paranoid of Chinese/North Korean expansion in the event of their rising threats.

The question to be asked is, why does China insist on maintaining secrecy in their recent maritime activity for a simple fishery? What is the purpose of locking up the reason behind such a large structure, equipped with a helipad in a place meant for only around 100 people? If China truly intends no foul play, then they should be in bold compliance with the concern of the Republic by acknowledging their apprehensions rather than downplaying and continuing to answer with an excuse as unclear as a “fish farm” and to allow for the investigation by South Korean officials to ease tensions. It would be wise for the Chinese government to eliminate all suspicion and government attention away from themselves, but the goal isn’t to ease the concerns, it’s to loop their age-old consistency of intimidation. 

Ultimately, the situation remains in development with talks of South Korea attempting on-site investigations of the oil rig, along with the current presence of the U.S. military in South Korea and the distraction of China in the progression of the Russo–Ukrainian conflict.
