WASHINGTON- The U.S. Trade Representative's office said late on Thursday it had begun Section 301 unfair trade practices probes of 60 economies in relation to what it called failures to take action on forced labor.

President Donald Trump's administration has sought to rebuild tariff pressure on countries around the world after the U.S. Supreme Court struck down his global tariffs as illegal on February 20.

"These investigations will determine whether foreign governments have taken sufficient steps to prohibit the importation of goods produced with forced labor and how the failure to eradicate these abhorrent practices impacts U.S. workers and businesses," U.S. Trade Representative Jamieson Greer said in a statement.

The list of 60 countries and economies includes some major U.S. trade partners and allies such as Australia, Canada, the EU, Britain, Israel, India, Qatar and Saudi Arabia. China and Russia are also on the list.

The government in Taiwan, which is listed too, said in a statement that it is committed to improving labor rights and preventing forced labor, and will work with the U.S. to emphasize human rights, resilience, and sustainable governance.

Trump imposed a 10% tariff for 150 days under Section 122 of the Trade Act of 1974 after the Supreme Court's ruling. On Wednesday, his administration said it was launching trade investigations into excess industrial capacity in 16 major trading partners.

The U.S. has already ​cracked down on solar panels and other goods ⁠from China's Xinjiang region under the Uyghur Forced Labor Prevention Act, signed into law by former President Joe Biden.

Greer said he wanted other countries to enforce bans on goods produced with forced labor similar to those enshrined in a nearly century-old trade law.

The U.S. alleges that Chinese authorities have established labor camps ​for ethnic Uyghur and other Muslim groups. Beijing denies allegations of abuse.

Greer said he hoped to conclude the Section 301 investigations, including proposed ​remedies, before Trump's temporary tariffs expire in July.
