A scenario involving Russia's military intervention in the events in Ukraine has been completely ruled out, Federation Council Speaker Valentina Matviyenko said.
"Such a scenario is not possible," Matviyenko told reporters on Wednesday.
"Russia stated, and reaffirms its position that we have no right, we cannot interfere in the internal affairs of a sovereign state," Matviyenko said.
The idea of a fast-track granting of the Russian citizenship and passports to Crimean residents is untimely, she said.
"I consider such an initiative untimely. This proposal must be carefully thought through and weighed," Matviyenko said. "So far (doing so) is inexpedient," she said.
"We are favoring Ukraine's integrity as a single state, and there should be no reason for separatist sentiments. We are keen on Ukraine, our closest neighbor, preserving its statehood," Matviyenko said.
Russia favors a peaceful resolution of the crisis, she said. "We are supporting the Ukrainian people. We share the Orthodox Christian faith, are linked by the same humanitarian space, blood relations, and our feelings extend to the whole Ukrainian people. Of course, we cannot be indifferent to the fate of ethnic Russians living in the Crimea. They account for over 60% of the republic's (Crimean) population," Matviyenko said.
The Federation Council will be watching further developments very closely and consider any infringement on the rights of nations and ethnicities inhabiting Ukraine unacceptable, she said.
"We set up a temporary commission that includes senators representing the regions adjacent to Ukraine, and we shall be monitoring the events in Ukraine on a daily basis. We shall draft our proposals and recommendations because this (situation in Ukraine) is alarming in the border areas," Matviyenko said.
"The authorities in Kiev must think about the state's integrity and not provoke separatist sentiments with their actions and decisions," she said.
Constitutional acts must be passed through referendum only, which is why the authorities in the country's eastern regions "are rightly saying that 'no one asked or consulted us on this matter," the speaker said.
"Decisions that are so fateful for the country must not be made by a handful of people in Verkhovna Rada," Matviyenko said.
