KYIV, Aug 28 – President Petro Poroshenko believes upgrading of Ukraine's credit rating by the Moody's Investors Service shows that the country has irrevocably embarked on the path of radical transformation.

"Over the past two and a half years, the Moody's Investors Service rating agency has upgraded Ukraine's credit rating from Caa3 ("negative outlook" in March 2015) to Caa2 ("positive outlook" in August 2017)... I am convinced that Ukraine has embarked on the path of radical reform and won't change its course!" Poroshenko wrote on his Facebook page on Monday morning.
