ROME — President Biden and other world leaders endorsed a landmark global agreement on Saturday that seeks to block large corporations from shifting profits and jobs across borders to avoid taxes, a showcase win for a president who has found raising corporate tax rates an easier sell with other countries than with his own party in Congress.
The announcement in the opening session of the Group of 20 summit marked the world’s most aggressive attempt yet to stop opportunistic companies like Apple and Bristol Myers Squibb from sheltering profits in so-called tax havens, where tax rates are low and corporations often maintain little physical presence beyond an official headquarters.

But it has become the centerpiece of Mr. Biden’s efforts to raise corporate taxes back home, in order to fund a sprawling domestic agenda that includes investing in child care and fighting climate change, and to shift the global balance of power toward American workers.
