WASHINGTON, Feb 20 (Reuters) - U.S. Trade Representative Jamieson Greer on Friday said ​his office would initiate ‌several new investigations under Section ⁠301 of the Trade ⁠Act of 1974, covering ‌most ‌major trading partners and areas such ​as pharmaceutical ‌product pricing.

Greer said the Trump administration was confident ​that all ​trade ‌agreements negotiated by President Donald Trump would remain in ⁠effect following Friday's decision ⁠by the Supreme Court to strike down tariffs ranging from 10% ⁠to ‌50% that were imposed ‌under the International Emergency ⁠Economic Powers Act.

He said the new investigations could address areas of concern such as industrial excess capacity, forced ​labor, pharmaceutical pricing practices, and discrimination against U.S. technology ​companies and ‌digital goods.
