Moscow, Russia (CNN) The Kremlin is expecting a "long and thorough meeting" between US President Donald Trump and Russian President Vladimir Putin at the G20 Buenos Aires summit later this month, Putin's foreign policy aide Yuri Ushakov said Friday, according to Russian state news agency RIA-Novosti.

Ushakov made the remark in response to a question about future meetings between Trump and Putin.

Before their tête-à-tête at the summit in Argentina, the two leaders are slated to meet on the sidelines of the 100th anniversary of the World War I armistice on November 11 in Paris, Ushakov said.

The US National Security Council told CNN that it had no announcement at this time.

Kremlin spokesman Dmitry Peskov has previously said that Putin expected to discuss Trump's plans to withdraw from the Intermediate-Range Nuclear Forces Treaty during their bilateral meeting in Paris.
