New fees on US ships arriving in Chinese ports came into effect on Tuesday, as trade tensions between Washington and Beijing increase.
The charges - which China says aim to "safeguard its shipping industry" from "discriminatory" measures - apply to US-owned, operated, built, or flagged vessels but not Chinese-built ships, state media said.
It comes in retaliation as the US is set to start charging fees on Chinese ships arriving in its ports from 14 October.
Beijing announced the levies last week alongside moves to tighten controls on its rare earth exports. US President Donald Trump responded with a threat of an additional 100% tariff on China.
Also on Tuesday, new US tariffs came into effect on imported timber, kitchen cabinets and upholstered furniture, much of which comes from China.
