"Both the article content and the time it was published are worthy of attention. It is a blatant manipulation, which will find its grateful readers to the west and east of Kyiv," Kuleba commented on Viktor Pinchuk's article in The Wall Street Journal.

Petro Poroshenko Bloc (PPB) MP, head of Crimean Tatar Mejlis Refat Chubarov said: "What Viktor Pinchuk shyly calls a 'painful compromise,' is in fact an invitation for us, Ukraine and Ukrainians, including Crimea and Crimean Tatars, to capitulation.
