The Office of the U.S. Trade Representative (USTR) on Monday launched seven days of public hearings on a plan to impose tariffs on another 300 billion U.S. dollars' worth of Chinese products.
Top U.S. officials have said that the levies, if imposed, would accelerate a move of manufacturing out of China.
During the first day of hearings, many U.S. companies said they have few alternatives other than China for producing clothing, electronics, and other consumer goods. Earlier, 600 U.S. companies, including one of the country's biggest retailers Walmart, sent a letter to the Trump administration, asking it to reconsider the new tariffs.
The hearings will end on June 25.
