"The United States and other Western nations had for months called for the ousting of Mr. Shokin, who was widely criticized for turning a blind eye to corrupt practices and for defending the interests of a venal and entrenched elite.He was one of several political figures in Kiev whom reformers and Western diplomats saw as a worrying indicator of a return to past corrupt practices, two years after a revolution that was supposed to put a stop to self-dealing by those in power."
Christine Lagarde, the managing director of the International Monetary Fund, which props up Ukraine financially, said last month that progress was so slow in fighting corruption that “it’s hard to see how the I.M.F.-supported program can continue.”
Steven Pifer is a career foreign service officer who was ambassador to Ukraine under President Bill Clinton and deputy assistant secretary of state for European and Eurasian Affairs under President George W. Bush. Pifer said "virtually everyone" he knew in the U.S. government and virtually all non-governmental experts on Ukraine "felt that Shokin was not doing his job and should be fired. As far as I can recall, they all concurred with the vice president telling Poroshenko that the U.S. government would not extend the $1 billion loan guarantee to Ukraine until Shokin was removed from office."
Anders Åslund, a resident senior fellow at Atlantic Council, a think tank in Washington, agreed that criticism of Shokin was widespread. Shokin "failed to prosecute anybody of significance, protecting both the Yanukovych circle and the Poroshenko group," Åslund said.

Daria Kaleniuk, the executive director of the Anti-Corruption Action Center, a leading anti-corruption voice in Ukraine, tweeted earlier this month that Shokin’s firing was not about protecting the company Hunter Biden was working for. The firing "was obviously not because the prosecutor wanted to investigate Burisma & Zlochevsky," she wrote.
