Lavrov arrived in Nicosia on Thursday to attend a foreign ministers' meeting of the Council of Europe at the end of Cyprus's presidency this month.
The Kremlin described as "complete nonsense" on Tuesday media reports that U.S. President Donald Trump had disclosed classified intelligence during a meeting with Russian officials.
USA intelligence officials have asked NBC News and other media organizations not to report the type of equipment, where it was stolen, and the name of the city where the intelligence was gathered, because doing so could harm US national security, they say.
"Truly I get the impression that many U.S. media are working in this vein".
Without directly confirming the details of their conversation, Lavrov said he didn't understand what the "secret" was since the USA introduced a ban on laptops on airlines from some Middle Eastern countries two months ago. But Trump told the Russians those things, the USA officials said, as he described intelligence that led to the new rules banning electronic devices in the cabins of certain flights.

"As far as I can recall, maybe one month or two months before the Trump administration had an official ban on laptops on airlines from seven middle Eastern counties and it was connected directly with the terrorist threat", Lavrov added.
White House officials reject the Post story, but they do not specifically deny that sensitive information came up at the meeting.
"Look at the way I've been treated especially by the media", the Republican billionaire said.
The Washington Post is reporting that Trump revealed highly classified information about Islamic State militants to Russian officials during a meeting at the White House last week.
However Russian President Vladimir Putin has dismissed the media frenzy surrounding Donald Trump's ties with the country as "schizophrenia" and offered to release details of the conversation between Trump and Sergei Lavrov to the US Congress.
This comes hot on the heels of reports that Trump shared classified information with Russian Federation about Isis.
