- Summary- Russia says it will not export oil subject to cap- Zelenskiy says price cap will do little to deter Russia- Ukrainian regions resort to scheduled blackouts- Ukrainian forces holding positions along front line -Zelenskiy- Russia says troops conducting successful operations in BakhmutKYIV, Dec 5 (Reuters) - A Group of Seven (G7) price cap on Russian seaborne oil came into force on Monday as the West tries to limit Moscow's ability to finance its war in Ukraine, though Russia has said it will not abide by the measure even if it has to cut production.Russian Deputy Prime Minister Alexander Novak called it a gross interference that contradicted the rules of free trade and would further destabilise the market.Industry players and a U.S. official said in October that Russia can access enough tankers to ship most of its oil beyond the reach of the cap, underscoring the limits of the most ambitious plan yet to curb Russia's wartime revenue.The United States and its allies have imposed sweeping sanctions on Russia and sent billions of dollars in military aid to Ukraine since Russia invaded on Feb. 24.Zelenskiy said Ukrainian forces were holding positions along the front line, including near Bakhmut in the east, viewed as Russia's next target in their advance through Donetsk region."
