China hits back on US port fees with retaliatory levies

China will slap port fees on U.S.-owned, operated, built, or flagged vessels on Tuesday as a countermeasure to U.S. port fees on China-linked ships starting the same day, China’s transport ministry said on Friday.
Later in the day, U.S. President Donald Trump said he was raising tariffs on Chinese exports to the U.S. to 100% and imposing export controls on critical software in a reprisal to export limits by China on rare earth minerals.
There are relatively few U.S.-built or U.S.-flagged vessels conducting international trade, but China will ensnare more ships by applying levies to companies with 25% or more of their shares or board seats held by U.S.-domiciled investment funds, analysts said.
