WASHINGTON, July 21 (Reuters) - U.S. Trade Representative Jamieson Greer on Tuesday said the Trump administration would soon unveil trade actions under Section 301 of the Trade Act connected to forced labor.

"We expect to see some action soon ... I can't really specify a timeline right now," Greer told CNBC when asked about a Financial Times report that the administration was expected to announce tariffs on dozens of countries soon as U.S. President Donald Trump's temporary 10% global tariff is scheduled to expire on Friday.

Section 301 of U.S. trade law is a provision that authorizes investigations into alleged unfair trade practices.

The U.S. government has been working on the new tariff strategy for months in a bid to rebuild tariff pressure after the U.S. Supreme Court struck down Trump's global tariff policy in February.

Brazil became the first country last week to be targeted under the strategy, after it was hit with 25% duties on its furniture, ethanol, machinery, footwear, sugar and other goods.
