Russian President Vladimir Putin will have more than one chance to chat in person with his American counterpart this month, the Kremlin said Friday, and there will be no shortage of issues to discuss.

Officials from Russia and the US said last month that plans were underway for a meeting when both leaders are in Paris on November 11, during which the Trump administration’s plans to withdraw from a decades-old arms treaty will be high on the agenda.

Kremlin foreign policy aide Yuri Ushakov said Friday that a longer meeting is expected when both leaders head to the Group of Twenty summit in Buenos Aires later in the month, RBC reported.

Discussions between Trump and Putin at the G-20 will be “lengthy and thorough” in contrast to the “brief” meeting in Paris, Ushakov said.

The Trump administration announced last month that it is planning to leave the Intermediate-Range Nuclear Forces Treaty. Critics say the landmark agreement has not been complied with by Russia and allows China to develop weapons that the US is prohibited from producing.

Russia’s foreign ministry said the potential decision would be a dangerous step, while US Defense Secretary James Mattis cautioned that a final decision has not been made by the president.
