Currently exist "no arrangements" for American leader President Trump to confer with Russian President Vladimir Putin "in the immediate future", a White House official has stated.
Recently Trump stated he and the Russian president would conduct negotiations in Hungary's capital within two weeks to discuss the ongoing hostilities.
A preparatory meeting between US Secretary of State Marco Rubio and his Russian counterpart Foreign Minister Lavrov was planned for recently - but the White House said the two had had a "constructive" call and that a meeting was not "necessary".
The White House declined to provide further information on the reason the negotiations had been delayed.
The US president had discussed a Hungarian meeting via telephone with the Russian leader, a just prior to meeting Ukraine's President Zelensky in the Oval Office.
Various sources claimed his talks with the Ukrainian leader had been a "contentious discussion", with insiders indicating the president had pressured him to relinquish large areas of Ukraine's east as part of a agreement with Moscow.
Nevertheless, on Monday the American president embraced a truce plan backed by Ukraine and EU officials to pause the war on the current front line.
"Leave it as is where it stands," he said.
Moscow has repeatedly pushed back against freezing the current line of contact.
The Russian government was only interested in "enduring stability", Russia's foreign minister commented on this week, implying that halting hostilities would only amount to a brief pause.
The "root causes" of the conflict required resolution, Lavrov said, using Kremlin shorthand for a set of extensive requirements that encompass the acceptance of complete Moscow control over the Donbas as well as the demilitarisation of the country – a unacceptable proposition for Kyiv and its Western allies.
Zelensky stated talks regarding the battle positions were the "start of negotiations" but that Moscow was "taking all measures" to evade negotiations.
He further commented the only topic that could make Moscow "take notice" was that of the provision of long-range weapons to the Ukrainian military.
The Russian president's unplanned conversation with the US leader recently occurred before reports that the United States was considering delivering long-range Tomahawk missiles to Ukrainian forces that could potentially strike Russian territory.
Zelensky stated it was the weapons consideration that had forced Russia to participate in talks. The discussion regarding the weapons systems had proven to be a "significant input" in international relations", he added.
