The talks proposed by France will only take place if Russia does not invade its neighbour, the White House said.
The meeting could offer a possible diplomatic solution to one of the worst security crises in Europe in decades.
US officials say intelligence suggests Russia is ready to launch a military operation, which Moscow denies.
The proposal was announced by the French presidency after two phone calls between President Emmanuel Macron and Mr Putin, which went on for almost three hours in total.
