Trump, who argues that high tariffs will revive American manufacturing, last year overturned decades of U.S. policy that favored lower tariffs and ever-freer trade. The administration initially proposed the forced labor tariffs last month. Forced labor is defined by the International Labor Organization Forced Labor Convention of 1930 as "all work or service which is exacted from any person under the menace of any penalty and for which the said person has not offered himself (or herself) voluntarily." "And yet I think it's undeniable that there is a significant response in terms of the adoption of import bans." European Union forced labor regulations due to go into effect later next year are also contributing, she said.
