According to a US administration official cited by Reuters, Trump's national security adviser John Bolton will discuss Iran's role in Syria during a meeting with his Russian counterpart, Nikolai Patrushev, in Geneva next week.
White House spokesperson Sarah Huckabee Sanders said Tuesday that this scheduled meeting was "a follow-up to the Helsinki summit to discuss a range of important national security issues."
The US official also told Reuters that Trump and Putin discussed arms control, including the New START treaty and the Cold War-era Intermediate-Range Nuclear Forces (INF) treaty, which banned nuclear and conventional ground-launched ballistic and cruise missiles with a range of 500 to 5,500 km (300 to 3,400 miles).
However, the official stressed that the leaders did not agree on a way forward on arms control, Reuters reported.
The US official said Trump has briefed Bolton, US State Secretary Mike Pompeo and US Ambassador to Russia Jon Huntsman about his one-on-one meeting with Putin.
Kremlin spokesman Dmitry Peskov declined to comment in early July on the claims that Bolton had asked Putin to make Iran withdraw its forces from Syria.
