President Donald Trump and his Russian counterpart, Vladimir Putin, are due to hold a summit on July 16 in Finland.
"I think that they will not avoid this issue as it is one of the most crucial problems today", Sputnik cited Syromolotov as saying.
The two leaders were scheduled to meet on July 16 for only the third time and in the first official U.S. -Russia summit since President Donald Trump was sworn into office in January of previous year.
The Kremlin said Putin did not plan to meet United States politicians who are visiting Russian Federation this week.
Trump and Putin will meet in Helsinki, Finland, on July 16, after Trump travels to the North Atlantic Treaty Organisation summit in Brussels, Belgium, and to the United Kingdom.
The US delegation is in Russian Federation until Thursday, ahead of the summit planned in Helsinki on July 16, at a time of high tension between Russian Federation and the West.
"So far there is no such meeting on the President's agenda, but we know that the American legislators have planned very extensive meetings with their colleagues."
MSNBC host Nicolle Wallace tore into President Donald Trump for dismissing the intelligence community's assessment that Russian Federation interfered in the 2016 election to help him win.
While the senior administration official said the summit must focus on carrying out a "sober assessment of the root causes" of problems in the US-Russia, the official also called the summit "a deliverable in itself".
The leaders are also likely to discuss New START, under which both nations cut their deployed strategic nuclear warheads to no more than 1,550, the lowest level in decades.
"The main rationale to have a bilateral meeting between Trump and Putin: Let them discuss these issues and see exactly where there might be room for progress, or where they might find there's no room at all", Bolton said on "Fox News Sunday".
