As part of President Zelenskiy’s hearts and minds strategy for the Donbas, the new government will hold an international investment forum on Oct. 29 in Mariupol, the largest seaport and industrial city in the region. Cut off for five years from half of the Donbas industries and mines, Mariupol has languished in every way — but population. Bolstered by Donetsk residents who do not want to live in the Russia-controlled half of the Donetsk, Mariupol’s population is believed to be back to its pre-Independence level of half a million.
