JAKARTA, Nov 10 (Reuters) - Russian President Vladimir Putin will not attend a gathering of leaders from the Group of 20 (G20) nations in person next week but may join virtually, officials from Russia and the host country Indonesia said on Thursday.Indonesia has resisted pressure from Western countries to withdraw its invitation to Putin and expel Russia from the group over the war in Ukraine, saying it does not have the authority to do so without consensus among members.Putin might take part by video conference though "the format of (his) participation is being worked out," Russia's state news agency RIA reported, citing a diplomat in the Russian embassy in Indonesia.Indonesian President Joko Widodo had been trying to mediate between global powers ahead of what will be the first meeting of leaders from the group since Russia invaded Ukraine in what Putin calls a "special military operation".The president told the Financial Times this week that Russia was welcome at the summit, which he feared would be overshadowed by a "very worrying" rise in international tensions."
