President Trump on Tuesday escalated his trade war by slapping 25 percent tariffs on $16 billion worth of Chinese imports, according to the US Trade Representative’s office.

The US will begin collecting tariffs on the Chinese goods on Aug. 23, targeting 279 import product lines.

About $50 billion in goods now face a 25 percent tariff in a widening trade war over China’s intellectual property practices and industrial subsidy policies.

China has vowed to match Washington’s tariff moves with duties on an equivalent worth of US products.
