(CNN) The Russian government is prepared to refute its meddling in the 2016 US presidential election when President Donald Trump and Russian President Vladimir Putin sit down for their first official summit next month, a Kremlin spokesman said Friday.

The two leaders will meet on July 16 in Helsinki, Finland, where they will discuss relations between the two countries as well as "national security issues," the White House has said.

"If the US President raises this issue, the Russian President absolutely will be ready to repeat once again that Russia had nothing to do with it and could not have anything to do with this thing that is surrounded by so many insinuations," Kremlin spokesman Dmitry Peskov told reporters Friday in Moscow.

He said that "serious preparation" was underway for the planned meeting between the two leaders but gave few new details on the agenda.

"It's a serious preparation. You know that many people are waiting for this summit, there is a very serious conversation on very complicated issues ahead," Peskov said in a conference call with reporters.
