Yushchenko and Obama could meet this autumn

He said that preparations for a possible meeting would be discussed during U.S. Vice President Joe Biden's visit to Ukraine on July 20-22.

"Preparations for a possible meeting between the two presidents in the near future, perhaps in autumn this year, will be one of the important elements during the visit," Yeliseyev said.

He also said that during Biden's visit to Ukraine, the sides would discuss the ways to step up a political dialogue at the highest level.

Upon Obama's election as U.S president, Yushchenko stressed the importance of strengthening cooperation with the U.S. counterpart and his team.
