and to refrain from any interference elsewhere in Ukraine," the White House

has concerns about the treatment of ethnic Russian and minority populations in Ukraine, the appropriate way to address them is peacefully through direct engagement with the government of Ukraine
and through the dispatch of international
observers under the auspices of the United Nations Security Council or the Organisation for Security and Cooperation in Europe (OSCE)," it said in a statement, adding the US
is ready to participate.

law, including Russia's obligations under the UN
Charter, and of its 1997 military basing agreement with Ukraine.

and the need to protect the rights of ethnic Russian and minority populations within Ukraine," the White House
"The Ukrainian government has made clear its commitment to protect the rights of all Ukrainians and to abide by Ukraine's international
commitments, and we will continue to urge them to do so," it said.
"In the coming hours and days, the United States will urgently consult with allies and partners in the UN
Security Council, the North Atlantic Council, the Organisation for Security and Cooperation in Europe, and with the signatories of the Budapest Memorandum," the White House
