BEIJING — China says it will retaliate if President Donald Trump goes ahead with tariff hikes on Chinese goods, ratcheting up tension ahead of negotiations in Washington.

The Commerce Ministry said Thursday that Beijing "will have to take necessary countermeasures" but gave no details of possible penalties.

Trump says he plans to raise tariffs on $200 billion of Chinese imports from 10% to 25%, effective Friday.

The volley of threats came as U.S. and Chinese negotiators prepared to meet in Washington for more talks aimed at ending a tariff war over Beijing's technology ambitions.
