The White House has said U.S. Vice President Joe Biden will travel to Ukraine on April 22, as it warned Russia against military escalation.
A White House statement said on April 12 that during his meetings with government leaders and civil society groups, Biden will "underscore the United States' strong support for a united, democratic Ukraine."
The statement said Biden and Ukrainian officials will consult on the recent events in eastern Ukraine, "where pro-Russian separatists, apparently with the support of Moscow, continue an orchestrated campaign of incitement and sabotage to destabilize the Ukrainian state."
Meetings will also address the short- and long-term energy security of Ukraine.
Earlier on April 12, Laura Lucas Magnuson, a spokeswoman for the White House National Security Council, said, "We call on President [Vladimir] Putin and his government to cease all efforts to destabilize Ukraine, and we caution against further military intervention."
