KIEV, Feb. 2 - U.S. oil major Chevron Corp. has been seeking to invest in developing shale gas deposits in Ukraine, Prime Minister Mykola Azarov said Wednesday.

“These are very difficult deposits to develop and we need very large investments,” Azarov said opening a meeting of the Cabinet of Ministers, according to a statement posted on the government’s Website.

“Chevron is ready to make [these investments] under two conditions, as they told us: political stability and unchanging rules of taxation,” Azarov said.
