BEIJING—President Donald Trump’s latest tariff hike on Chinese goods took effect on May 10 and Beijing said it would retaliate, escalating a battle over China’s technology ambitions and other trade strains.
The Trump administration raised duties on $200 billion of Chinese imports from 10 percent to 25 percent. “China deeply regrets that it will have to take necessary countermeasures,” said a Commerce Ministry statement which gave no details.
