China announced sanctions on Tuesday (October 14, 2025) against five U.S.-linked subsidiaries of South Korean shipbuilder Hanwha Ocean amid trade tensions between the world's two largest economies, sending the company's shares sharply lower.
The move, announced by the Chinese Commerce Ministry, comes on the day that China and the U.S. implement additional port fees targeting each others' vessels, although China has exempted ships it built.
Organisations and individuals within China are prohibited from engaging in any transactions, cooperation or related activities with these Hanwha entities, the Ministry said in a statement.
"Hanwha Ocean's U.S.-related subsidiaries have assisted and supported the U.S. government's relevant investigative activities, thereby jeopardising China's sovereignty, security, and developmental interests," the statement said, without elaborating.
Hanwha did not immediately respond to a Reuters request for comment.
