Putin insists on territorial concessions, demands all of Donetsk Oblast

"Russian President Vladimir Putin remains committed to seizing all of Donetsk Oblast by

force, the sources said. Moscow also plans to retain occupied border areas of Ukraine's Sumy and Kharkiv oblasts as a buffer zone. Bloomberg's sources said the Kremlin's position hardened amid intensifying Ukrainian strikes deep inside Russian territory, including on Moscow, which have damaged oil refineries and caused fuel shortages. An additional factor was Trump's approval of a new sanctions bill targeting Russia, which would impose tariffs of up to 100% on the five largest buyers of Russian oil and gas." msn
