Majority of 130 witnesses voice strong opposition to Trump's proposed tariffsUS businesses expressed concerns over the White House's strategy to address the trade relationship with China, urging discretion by the US trade representative (USTR), as three days of public hearings concluded on Thursday in Washington. The possibility of seeking alternative sourcing markets outside of China was the most commonly raised question to US businesses by the hearing committee headed by the USTR, Department of Commerce and Department of Labor. But US businesses are most concerned that they would have to pass any increased costs on to their customers. The USTR published a report in April this year highlighting the office's efforts to "press China on a range of issues affecting the pharmaceutical sector". The next step is for the USTR to review the written submissions from witnesses and present its findings to the administration.
