Several Asian countries could soon face additional duties on some of their exports to the U.S. following Washington's probe into imports produced using forced labor, the Office of U.S. Trade Representative (USTR) said Tuesday.

The USTR said Bangladesh, Cambodia, China, Hong Kong, India, Japan, Malaysia, the Philippines, Singapore, South Korea, Sri Lanka, Taiwan, Thailand, Indonesia, Pakistan, and Vietnam are among the 54 economies that have failed to impose and effectively enforce a forced-labor import ban.

The USTR proposed a 10% additional tariff for economies that have partially enforced bans on the importation of certain forced-labor goods and a 12.5% tariff for the rest.
