"The bill [Ukraine Freedom Support Act] gives the [US] administration authorization for a broad set of tools, that also allows considerable possibility to use those tools in a matter that is flexible and just keep an eye on how the situation develops," Victoria Nuland said during the event at the American Enterprise Institute in Washington, DC.
"Ukraine Freedom Support Act is emblematic of the strong bipartisan bicameral support for Ukraine and its aspirations across the United States," Nuland said.
White House spokesperson Josh Earnest said on Tuesday that Obama intended to sign the Ukraine Freedom Support Act by the end of the week.
The bill stipulates providing lethal assistance, as well as aid in energy and defense sectors, as well as civil society to the Ukrainian government and imposing a new round of economic sanctions on Russia.
The United States, as well as the European Union and a number of other countries, have introduced several rounds of sanctions against Russia in recent months, targeting its banking, energy and defense sectors, over Moscow alleged involvement in the Ukrainian crisis, although Russia has denied the allegations.
