China takes steps against US-linked units of S.Korea shipbuilder Hanwha

China has taken countermeasures against five U.S.-linked subsidiaries of South Korean shipbuilding firm Hanwha Ocean, the Chinese commerce ministry said on Tuesday.

Organisations and individuals within China are prohibited from engaging in any transactions, cooperation or related activities with these 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.

Hanwha did not immediately respond to a Reuters request for comment.

The move 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.

U.S. President Donald Trump's administration announced earlier this year plans to levy fees on China-linked ships to loosen Beijing's grip on the global maritime industry and bolster U.S. shipbuilding.

China hit back last week saying it would impose its own port fees on U.S.-linked vessels on the same day then U.S. fees come into effect.

China has called U.S. measures targeting its maritime, logistics, and shipbuilding industries a serious violation of international law and fundamental norms of international relations.
