Earlier, Hungary's finance minister said Budapest would hold up a final deal on a $US50 billion ($A74 billion) G7 loan to Ukraine until after the US presidential election by delaying its decision on the timing of the renewal of EU sanctions against Russia.
Speaking at a briefing in Strasbourg, Orban said on Tuesday that US Republican presidential candidate Donald Trump, if elected, would not wait until his inauguration but would start working for peace in Ukraine right after the November 5 election, adding that European leaders would have to react to that.
Orban, who has long endorsed Trump, also said that both direct and indirect communications were needed between the warring parties and it was a part of international politics that a third party mediates between them.
"We don't want to block anything, we just want to convince European leaders to change their strategy (on Ukraine) because the current strategy does not work," Orban said.
Days after Hungary took over the EU's rotating presidency in July, Orban set out on a self-styled peace mission which included a visit to Moscow and Kyiv and also Trump, and triggered a backlash from European leaders.
Orban said his country wanted a normal economic relationship with Russia in areas not affected by sanctions.
Hungary relies heavily on Russian crude and gas imports, and Russia's Rosatom is also building a nuclear power plant in Hungary.
"We are transparent, we do what we say. And we think that in the areas where there are no sanctions between the EU and Russia naturally we would like to have normal economic relations with Russia," Orban said, accusing some Western peers of "hypocrisy", citing how much oil and gas they had bought from Russia. He did not name the countries.
Orban's press conference was briefly interrupted by a politician from the opposition Democratic Coalition, who ran into the room shouting and accusing Orban of "betraying" his country, selling it out to Russia and China.
He was escorted out by security.

Meanwhile, NATO Secretary General Mark Rutte warned on Tuesday that Ukraine could be "facing its toughest winter" yet since the full-scale Russian invasion began in February 2022.
With Russia carrying out "massive strikes" against Ukraine's energy infrastructure, Rutte said he would push for more military aid at an upcoming meeting of the Ukraine Defense Contact Group - a United States-led body soon to be absorbed into NATO - in Germany.
The top NATO official, who took office last week, was speaking at alliance headquarters in Brussels alongside Finnish President Alexander Stubb, the first NATO leader to visit the new secretary general.
Stubb called on NATO allies - singling out the United States - to lift restrictions on Western weapons supplied to Ukraine to allow for targets to be hit inside Russia.
Ukraine must be able to "fight this war without one hand behind its back," Stubb said.
Ukraine's backers including the US have so far denied these requests fearing an escalation in the conflict.
