"By law the [start of] the presidential election campaign must be announced in late November-early December, I think", he said.
Russian President Vladimir Putin said he has no personal ties to his American counterpart Donald Trump as he lamented the crisis in relations between the former Cold War rivals.
"No. Neither have I taken a decision who I will stand against, nor have I taken a decision if I will run for president at all", he said answering questions at a plenary meeting of the Russian Energy Week.
After the court ruling, Navalny tweeted: "20 days in jail".
Putin has been president or prime minister since 1999, maintaining his power by in effect silencing independent media and placing Kremlin-controlled restrictions on election laws. Navalny on Wednesday called for another round of nationwide protest on that day in his absence.
Severe Tension With U.S. "As far as bilateral ties with the United States are concerned, their current level can not be satisfying", Putin said at the Kremlin after he received diplomatic credentials from Huntsman. Trump's rhetoric doesn't help.
"Russia's energy balance is one of the cleanest among the world's largest economies", the president said while addressing a plenary session of the Russian Energy Week (REW), which kicked off in Moscow on October 3.
Moreover, Russia's Energy Minister Alexander Novak has said that Libya is also expected to join the OPEC deal.
While Russia and a USA -led coalition are both targeting Islamic State (IS) fighters with air strikes in Syria, Russia has strongly backed President Bashar al-Assad's government throughout the six-year war there while the United States backs rebels.
Putin said Russia had more reason than most to be concerned by Pyongyang's atomic weapon program, saying that North Korea's nuclear testing range was located just 200 kilometres (124.27 miles) from the Russian border.
"Those who try to speak to North Korea from a position of strength only shore up the North Korean regime", Putin said.
