G7 nations have failed to agree on a proposal by Britain for sanctions against Russia in the wake of a deadly chemical attack they say was carried out by Moscow's ally, Syria, APA reports quoting BBC.
Italy's foreign minister said the group did not want to back Russia into a corner and preferred dialogue.
US Secretary of State Rex Tillerson has moved on from the G7 meeting in Italy and has arrived in Moscow for talks.
He insisted Syria's president could not play a part in the country's future.
The G7 meeting in the Italian city of Lucca followed last week's chemical attack on the rebel-held Syrian town of Khan Sheikhoun that left 89 people dead.
The Turkish health ministry on Tuesday confirmed that the nerve agent, sarin, had been used.
Syria denied the attack but the US then carried out a retaliatory strike, firing 59 cruise missiles at a Syrian airbase.
