'Pursuing every avenue' to roll back discriminatory taxes -Yellen

Yellen told the Senate Finance Committee she had engaged in "very constructive" bilateral conversations with the Irish finance minister on the issue, and believed the entire European Union would ultimately support an increase in global minimum taxes, as proposed by the United States.

She said she was hoping for progress on the tax issue - which is being negotiated under the leadership of the Organization for Cooperation and Development - by the time the leaders of the Group of 20 major economies meet in October.

U.S. President Joe Biden and other leaders of the Group of Seven (G7) advanced economies on Sunday endorsed a commitment by G7 finance officials to work toward a global minimum tax of at least 15% through the G20/OECD inclusive framework.
