WASHINGTON, Feb 23 (Reuters) - Katherine Tai, President Joe Biden's pick to revamp U.S. trade policy to focus on workers and "ordinary Americans" over corporations, will get a chance to explain what that will mean in practice at her confirmation hearing on Thursday.
Tai's testimony before the Senate Finance Committee has been anxiously awaited for months by industry, U.S. trading partners from Beijing to Brussels, labor groups and lawmakers - all in a long queue to lobby Tai as soon as she is confirmed.
As U.S. trade representative, or trade "czar," for the world's largest economy, biggest importer of goods and second largest exporter after China, Tai will wield immense clout, especially after four years of trade turmoil sown by former President Donald Trump.
Tai, the top trade lawyer for the House of Representatives Ways and Means Committee, is seen as a tireless and unflappable negotiator and deeply knowledgeable about China. She recently won praise for getting tougher labor and environmental standards added to the U.S.-Mexico-Canada trade deal.
She has been guarded about her specific plans, but industry officials and congressional aides say one thing is clear - she will add labor concerns to the equation.
In January, Tai told the National Foreign Trade Council that U.S. trade policy must be "worker centric," focusing on people as wage earners and not just consumers - a key message repeated often by other top Biden economic policy experts.
In Geneva, the U.S. delegation recently spoke up with concerns about Myanmar's record of violating labor rights and using forced labor - a statement administration officials say reflects an increased focus on workers at home and abroad.
The incoming director of the World Trade Organization, Ngozi Okonjo-Iweala, said Biden's trade officials agree with her about the need to make trade relevant to everyday people to rebuild confidence in the global trade body and the global economy.
While Britain, Kenya, Japan and others are clamoring for new or expanded trade deals, the Biden administration has put any new negotiations on hold until after a comprehensive review of all Trump trade policies.
For now, Tai will focus on enforcing existing trade deals, including provisions aimed at protecting workers that she herself helped add to the U.S.-Mexico-Canada trade deal.
One European official said Brussels was waiting to see how Tai will implement Biden's pledge to rebuild ties with allies.
"We hope to start seeing the first signs of how she will make this happen. And of course: putting disputes to bed ASAP," the official said.
Tai has a long list of disputes to resolve over Trump's tariffs on steel and aluminum, aircraft and wine, and threatened duties over digital services taxes.
"Her job ... will be to reassure the senators she’s going to be tough on the other countries that are taking advantage of us," said William Reinsch, a trade expert at the Center for Strategic and International Studies in Washington. "She will be expected to take a hard line on China," he said.
Senate Finance Committee Chairman Ron Wyden has pledged to move Tai's nomination quickly, which means she could get a Senate vote by next week or the following week, making her the earliest USTR confirmed in the job since the early 1990s.
TRADE 'REGULAR ORDER'
The U.S. Chamber of Commerce on Wednesday endorsed Tai in a letter to Wyden and the committee's top Republican, Senator Mike Crapo, saying Tai needed to restore "regular order" to U.S. trade policy, consulting with business, labor and other groups.
"The next USTR must avoid the use of tariffs as a blunt instrument, and must avoid inaction on trade agreements as well," wrote Myron Brilliant, the chamber's head of international affairs.
Ken Monahan, trade policy chief for the National Association of Manufacturers, said he expects Tai would play a key role in shaping trade policy, in consultation with Treasury Secretary Janet Yellen, national security adviser Jake Sullivan and Secretary of State Antony Blinken.
"When it comes to trade actions and negotiations, I have no doubt that Katherine will be in the driver's seat," he said. (Reporting by David Lawder and Andrea Shalal; Editing by Leslie Adler)
