After a 10 percent tariff on Chinese products took effect on Tuesday, China announced retaliatory measures, including tariffs and an investigation of Google.

The World Trade Organization said China submitted a request for consultations with the U.S. on the tariffs. China said the duties are discriminatory.

The world’s two largest economies did not cut a deal to avert sweeping U.S. tariffs, which came into effect after midnight. Beijing immediately retaliated.
