THE US will walk away from brokering peace talks between Ukraine and Russia unless there is a deal within days, Trump's Secretary of State warned.
Marco Rubio, speaking in Paris, said talks needed to progress "very quickly now" and gave a "matter of days" as a deadline.
Rubio said: "We're not going to continue with this endeavour for weeks and months on end.
"So we need to determine very quickly now, and I'm talking about a matter of days whether or not this is doable in the next few weeks.
"If it is we're in. If it's not, then we have other priorities to focus on as well."
Trump's team has spent weeks trying to broker a ceasefire between Russia and Ukraine, and are frustrated by the continuing fighting.
Last week, Trump issued a blistering warning to Putin to "get moving" with accepting negotiations.
Rubio reiterated the urgency following a marathon day of talks among US, Ukrainian and European diplomats.
It was the first time with Trump in charge that officials from those three groups are known to have met to discuss an end to the war.
He said the conversations had been positive and pathed the way for peace.
Another similar meeting is expected in London early next week, according to French officials, but Rubio said he couldn't make it.
Rubio and presidential envoy Steve Witkoff have helped lead US efforts to seek peace.

Several rounds of negotiations have been held in Saudi Arabia, and Witkoff has met with Putin three times.
Moscow has effectively refused to accept a comprehensive ceasefire that Trump has pushed and Ukraine has endorsed.
The UK is considering sending troops to Ukraine for a period of years in order to keep the peace.
France has also revealed they are considering "mobilising civilians" to counter a looming Russian threat
The Kremlin has warned that any Nato interference would mean war.
Putin's puppets have been raging over the Paris talks.
Russian Security Council Deputy Chairman Dmitry Medvedev fumed that "Ukraine’s fascist clique have come to Paris for talks with the UK, Germany and France".
He taunted that they were discussing "how many European coffins they will be ready to accept after the deployment of the troops of the `coalition of the willing’ in Ukraine".
The conversations in Paris come as minerals deal between the US and Ukraine looks set to be signed next week.
The two nations will begin a new round of negotiations on April 24, Ukraine's deputy minister of economy told the national broadcaster on Friday.
Taras Kachka said: "We are trying to resolve many technical issues online and in writing in order to narrow them down to the most sensitive issues that will require a political decision."
Meanwhile, Russian bombs continue to slaughter civilians in Ukraine.
A vicious "double-tap" missile attack on Sumy killed at least 35 on Palm Sunday.
World leaders slammed the attack, with Zelensky branding Putin a "b***ard" for deliberately targeting civilians.
He urged the world not the remain "silent" or "indifferent" to the violence, and called for "really strong pressure" against Russia.
Another lethal missile and drone attack terrorised Ukrainians today, on Good Friday.
