U.S. President Donald Trump has threatened to impose a 50% tariff on China, after a report on Sunday that Beijing was preparing a weapons shipment to Iran.

May, told China that they are welcome to buy oil from America or Venezuela while the U.S. is embargoing Iran, and if they try to continue buying oil or sending weapons to Iran, he will impose a "staggering" tariff.

The president threatened ships that attempt to come close to the U.S. naval blockade will be “immediately ELIMINATED.”
