The move followed the U.S. decision to impose steep fees on Chinese ships docking at American ports https://t.co/jB2i0OpjL8

US China tensions are no longer contained but spreading to allies. China is placing limits – forbidding any individual or entity from doing business with five US entities of South Korea’s Hanwha Ocean Co, following China levying fees on American ships docking at its ports…

Impact:
5) Near zero, not many ships were built in the US or 0.2% of shipbuilding
4) Minimal – about 80 vessels across all times1 to 3 has very high impact as a US listed firm is also vulnerable.
Costs too high to make it profitable so huge disruption to global trade. About…— Trinh (@Trinhnomics) October 14, 2025
One last note on shipping before I go. First, China added exemptions to Chinese-built vessels after realizing that it will add to costs. Second, the US, which started studying into section 301 for shipbuilding since Biden and then continued with Trump started imposing fees on…

China just changed the rules again. These new sanctions go straight into the bloodstream of global trade. They don’t make a statement. They redraw the map.
The move against five American-linked branches of South Korea’s Hanwha Ocean Co says everything about where this conflict has gone. Beijing didn’t punish them for breaking rules. It punished them for helping Washington look for answers. For assisting investigators. For getting too close.
“These subsidiaries have assisted and supported relevant U.S. government investigations and actions, thereby endangering China’s sovereignty, security and development interests.”

That single sentence means any company that helps the United States can lose access to China’s ports overnight. Hanwha Ocean America in Houston, Hanwha Ocean USA in San Diego, Hanwha Ocean Defense Systems in Norfolk, Hanwha Ocean Marine Engineering in New York, Hanwha Ocean Procurement Services in Connecticut — these aren’t small offices. They keep the machinery of shipbuilding, defense supply chains, and contracts moving. Cutting them off sends a message to every boardroom on the Pacific Rim.
Then came the port rules. Beijing now applies special fees to ships with American fingerprints. It looks simple until you read the fine print.
If the vessel is owned by an American company.
If it’s operated by one.
If an American group holds a quarter of its shares or control.
If it sails under the U.S. flag.
If it came out of an American shipyard.
Each line catches thousands of ships. Lloyd’s Register says more than 18,000 vessels fit somewhere on that list. If half face extra fees or need new routes, freight prices rise. Insurance jumps. Delivery schedules crack. That kind of disruption moves fast and leaves no easy fix.
“China just weaponized shipbuilding… Beijing is signaling it will hit third-country firms that help Washington counter China’s maritime dominance.”

The United States still calls this tit-for-tat, but the shape is different now. Washington investigates Chinese dominance in shipbuilding. Beijing rewrites the rules of entry for the global fleet. It’s like one side brought paperwork to a knife fight.
“The US move is a typical act of unilateralism and protectionism… seriously undermining [China’s] interests.”

Markets already feel it. Hanwha’s shares fell hard. Port authorities in Singapore and Rotterdam expect a surge in rerouted ships. Insurers rewrite risk premiums by the hour. Trade lawyers build new language into contracts, trying to protect clients from a kind of political weather that can’t be forecast.
This is where the illusion of cooperation ends. China and the United States built a world economy together and are now tearing it apart piece by piece. The split runs through shipyards, shipping lanes, insurance desks, and even retirement funds. What started as tariffs has turned into a structural divide, and nobody seems ready for what it means when the two largest economies stop sharing a map.
