LONDON, Aug. 26 - Increasingly sour rhetoric with Russia is not deterring investors in Ukraine, who are betting that Western powers will guarantee enough financial aid to shield the country’s troubled economy from investment risk, Reuters reported.

Western powers are aware of a delicate strategic balance in Ukraine, and although they may not be willing to allow Ukraine into NATO or the European Union any time soon, neither do they want total financial failure or default in a country that lies astride key energy routes and dominates the Black Sea.
