China Retaliates Against U.S. Shipbuilding Efforts, Sanctions South Korean Firm Hanwha Ocean
Table of Contents
China’s Commerce Ministry announced Tuesday a ban on transactions between Chinese companies and five subsidiaries of South Korean shipbuilder Hanwha Ocean, escalating tensions in a burgeoning trade dispute centered on the global shipbuilding industry. The move, widely viewed as a direct response to the U.S.’s efforts to revitalize its domestic shipbuilding capacity, signals a willingness by Beijing to target firms supporting Washington’s initiatives.
The Chinese ministry also revealed it is investigating a U.S. probe into China’s dominance in world shipbuilding and warned of further retaliatory measures. According to the ministry, the U.S. investigation poses a threat to China’s national security and its shipping industry, citing Hanwha Ocean’s involvement as a key concern. The U.S. Trade Representative initiated the Section 301 trade investigation in April 2024, concluding that China’s strength in the sector burdens U.S. businesses.
“China just weaponized shipbuilding,” stated Kun Cao, deputy chief executive at consulting firm Reddal. “Beijing is signaling it will hit third-country firms that help Washington counter China’s maritime dominance.”
Rising Tensions in Global Shipbuilding
The escalating dispute adds another layer of friction to the complex relationship between Washington and Beijing, with both sides recently imposing new port fees on each other’s vessels, effective Tuesday. This latest exchange underscores the intensifying competition for control of the global shipbuilding market.
South Korea and the U.S. have been strengthening their collaboration in shipbuilding as a countermeasure to China’s leading position as the world’s largest shipbuilder. This strategic alliance is exemplified by Hanwha Ocean’s recent investments in U.S. shipbuilding infrastructure.
Hanwha Ocean’s U.S. Expansion and the Chinese Response
In late 2024, Hanwha Ocean acquired the Philly Shipyard in Pennsylvania for $100 million. The company subsequently announced plans in August to invest $5 billion in new docks and quays, directly supporting U.S. efforts to restore a globally competitive shipbuilding capacity.
Last year, Hanwha Ocean also secured contracts with the U.S. Navy to provide maintenance, repair, and overhaul services for U.S. naval vessels. The company acknowledged the Chinese government’s announcement, stating via email that it is “closely reviewing its potential business impact.”
The sanctions immediately impacted Hanwha Ocean’s stock price, with shares trading in South Korea falling as much as 8% on Tuesday before closing 5.8% lower. South Korea’s Foreign Ministry indicated it is assessing the potential effects of the sanctions on Hanwha companies and related industrial sectors, pledging to “communicate with relevant ministries, industry representatives and the Chinese side to minimize damages resulting from these measures.”
The sanctioned entities include Hanwha Shipping LLC, Hanwha Philly Shipyard Inc., Hanwha Ocean USA International LLC, Hanwha Shipping Holdings LLC, and HS USA Holdings Corp.
Trade War Concerns and Potential for Escalation
The current escalation raises concerns that a fragile truce in the broader trade war between the world’s two largest economies is unraveling. U.S. President Donald Trump recently threatened a new 100% tariff on imports from China, fueled by frustration over Chinese export controls on rare earths. This has cast doubt on the possibility of a planned meeting between Trump and Chinese leader Xi Jinping later this month. However, Beijing stated on Tuesday that communication channels between the two countries remain open, with working-level talks held on Monday.
China’s new port fees will apply to ships owned by U.S. companies, entities with a U.S. stake of 25% or more, vessels flying the U.S. flag, and those built in the United States – mirroring the U.S.’s recently imposed fees on Chinese ships. Despite China’s dominance, U.S. businesses currently represent only 2.9% of world fleet ownership by capacity and 0.1% of global shipbuilding tonnage. Trump has consistently vowed to rebuild the U.S. shipbuilding industry as part of a broader strategy to expand U.S.-based manufacturing. Currently, China accounts for over half of all new shipbuilding, with South Korea holding approximately 30% and Japan just over 10%. Hanwha Ocean announced its withdrawal from a joint venture in China in May.
