KIEV, March 20 – U.S. President Barack Obama has invited President Viktor Yanukovych – along with 50 other world leaders – to join a nuclear non-proliferation summit in Washington on April 12, Dzerkalo Tyzhnia weekly reported Saturday citing a source.

Ukrainian diplomats are currently trying to secure an Obama-Yanukovych meeting, but the source said such a meeting was unlikely because of Obama’s busy schedule as the host of the summit.
