Despite the dreary outlook, Trump said that he heard that Secretary of State Rex Tillerson had a positive meeting with Russian officials.
Putin accused Assad's opponents of planning to stage chemical attacks to be blamed on Damascus in order to lure the United States deeper into the conflict.
This is the eighth time during Syria's six year civil war that Moscow has used its veto power on the Security Council to shield Assad's government.
"It reminds me of the events in 2003 when US envoys to the Security Council were demonstrating what they said were chemical weapons found in Iraq", Putin said. "It wasn't only a violation of the laws of war but it was a - we believe, a war crime", Toner said. Ten countries voted in favor of the text, while Bolivia joined Russian Federation in voting no. We're a very, very strong country.
"So far we have not seen any facts".
Mr Johnson said: "This afternoon in NY, the global community sought to make clear that any use of chemical weapons by anyone anywhere is unacceptable and that those responsible will face consequences". He wants to hold a new round of talks in May.
At the White House press conference, Trump, who has repeatedly questioned NATO's objective, also said the Western military alliance is "no longer obsolete". "I said it [Nato] was obsolete". Trump, in the past, has called Assad "evil" and "an animal".
"The principle of "innocent until proven guilty" has to be respected", Lavrov said.

Russian Federation called for an impartial investigation into the chemical weapon attack and said moving towards regime change in Syria would only destabilize the region.
On Wednesday Russia vetoed a UN Security Council resolution demanding a swift investigation into a chemical weapons attack in Syria, challenging claims that Assad was behind the chemical attack.
In an interview Tuesday with Fox Business Network, Trump said the U.S.is "not going into Syria" and said last week's missile strike was a direct response to images of dying children he saw after the sarin attack.
Relations between Russian Federation and the United States are at an "all-time low", according to US President Donald Trump.
The two sides spoke of the low-level of trust between them and the USA, noting it's an unacceptable state of strain between the world's two biggest nuclear powers.
The toxic gas attack on April 4 prompted the United States to launch missile strikes on a Syrian air base and widened a rift between the United States and Russian Federation.
During a joint press conference Wednesday, Tillerson said the two had a "lengthy exchange of views regarding the situation in Syria and shared perspectives on possible ways forward".style="text-align: center;"
