"The US will continue to impose costs on Russia for its illegal and illegitimate occupation of Crimea and, moreover, that we are fully prepared to impose additional significant sanctions on Russia if it continues to escalate the situation in Ukraine," US Treasury Secretary, Jacob Lew, said.
Address the annual Spring meeting of the International Monetary Fund and the World bank, Lew said there was broad and strong unity within the G-7 on increasing the sanctions and costs in response to escalating action from Russia.
"The IMF, which has assumed a leading role in the global response, has forged a preliminary agreement with Ukraine on a sizable loan program. And on Monday, I will sign a declaration moving forward a USD 1 billion loan guarantee agreement with Ukrainian Finance Minister Shlapak," Lew said.
Earlier in the day, the Treasury's Office of Foreign Assets Control (OFAC) slapped sanctions against Crimean separatist leaders and Crimea-based gas company Chernomorneftegaz for being responsible for or complicit in, or having engaged in, actions or policies that undermine democratic processes or institutions in Ukraine.
New satellite images released by NATO showed Russian troops amassed on the Ukrainian border.
"It is clear from the satellite images released by NATO yesterday that Russia has poised a menacing force near the Ukrainian border as part of its effort to destabilize Ukraine and destroy its chance for independence, self-determination, and democracy," Senator John McCain said.
White House Press Secretary Jay Carney, told reporters, meanwhile, "We call on (the Russian) President (Vladimir) Putin and his government to cease all efforts to destabilizse Ukraine, and we caution against further military intervention. We remain prepared to impose further costs on Russia for its actions or further provocations".
"We have not seen evidence of what the foreign minister or others are referring to in terms of incursions or aggressive actions by the Ukrainian Government; quite the contrary," she said.
