The Kremlin hopes a planned meeting between Russian President Vladimir Putin and his US counterpart Donald Trump this week will establish an effective working dialogue between them.
Such a dialogue was needed between Washington and Moscow to help resolve conflicts around the world, the Kremlin said.
The meeting, due to be held on the sidelines of a G20 summit in Hamburg on Friday, will explore whether there is a possibility and readiness for the two countries to fight international terrorism together in Syria, Kremlin spokesman Dmitry Peskov told a conference call with reporters.
"This is the first meeting, the first time the two Presidents will get acquainted - this is the main thing about it," Mr Peskov said.
"The expectation is that a working dialogue will be established, which is vitally important for the entire world when it comes to increasing the efficiency of resolving a critical mass of conflicts."
He said Mr Putin would also use what will be his first face-to-face meeting with Mr Trump to explain Moscow's stance on the conflicts in Syria and Ukraine.
But he said the brief format of the meeting meant the Russian leader might not have enough time to give a full analysis of the causes of the conflict in Ukraine.
Three years after Russia annexed Crimea from Ukraine and a pro-Russian separatist uprising broke out in eastern Ukraine, there is little sign of a peaceful solution in the east despite a ceasefire agreement signed in February 2015 in Minsk, Belarus.
Those accords were signed by France, Germany, Russia and Ukraine. Kiev accuses Moscow of actively supporting the pro-Russian separatists. Russia denies the charge.
The meeting with Mr Trump would "be a good chance to reiterate Russia's stance that the Minsk accords have no alternative, that the Minsk accords must be implemented, and that measures must be taken to stop provocations which unfortunately Ukraine's armed forces are still carrying out", Mr Peskov said.
The two leaders' first meeting is highly anticipated, coming as investigations continue into possible collusion between members of Mr Trump's presidential campaign and Russian officials and as relations between Moscow and Washington are being described as at their worst since the Cold War.
The White House said no formal agenda had been set out for Friday's talks, though Mr Trump was said to be keen to promote co-operation over the North Korean threat and Syria.
