Anti-EU Le Pen is among European politicians who have called for closer ties with Putin and approved of Moscow's annexation of Crimea from Ukraine in 2014, which saw the United States and European Union slap sanctions against Russian Federation.
Le Pen has long expressed admiration for Putin, even telling a Russian newspaper in 2011 that "I admire Vladimir Putin", and Le Pen's National Front Party received a $9.7 million loan from a Russian bank in 2014.
"I have always called for lifting the sanctions, which are counterproductive".
"I can assure you for 100% that we will not be financed from Russian Federation", he said on Friday morning.
"I do hope that France will be able to achieve a solution when we will be able to cancel the blacklists at least on the territory of our country".
"We reject the diplomacy of threats, the diplomacy of sanctions, the diplomacy of blackmail that the European Union has been using increasingly often, not only against Russian Federation, but also against its own members", the French politician noted.
The French politician, who has said she would hold a Brexit-type referendum on leaving the European Union, also toured a Kremlin exhibition of France's past imperial glory under King Louis XIV. France is paying a great price because of terrorism. While Republican rival Francois Fillon has said he would seek to rebuild ties with Russia, Le Pen has outdone him in calling for close relations.
The National Front has previously taken a loan from a Russian bank, but officials from the party and Putin's spokesman said this trip was not a cash-raising exercise.
Opinion polls show Le Pen getting through to the second, decisive round of the French presidential election on May 7 but then losing to centrist candidate Emmanuel Macron.
Her campaign treasurer Jean-Michel Dubois didn't respond to a text message asking if she plans to meet with potential lenders during the Russian visit.
Le Pen is expected to easily make it to the second round of voting on 7 May, as she is now neck-and-neck in first round voting intentions with centrist candidate Emmanuel Macron.
Friday's encounter lasted an hour and a half, Le Pen advisor Ludovic de Danne wrote on Twitter.
A Russia-friendly approach to geopolitics runs in the Le Pen family.
"She's not the only candidate to be in favor of better relations with Russia - (François) Fillon is, too".
In an interview previous year with CNN, Le Pen said she was left with no choice after French banks turned her down.
