The official also rejected security concerns about allowing Russian officials into the Oval Office, including Kislyak, who is widely considered to be a spy by United States intelligence officials. Lavrov is the highest-ranking Russian official Trump has met with so far as president.
The meeting will take place at 10:30 am and will be strictly closed to press, according to the White House.
"The previous administration bent over backwards to undermine the solid foundation of our relations", Mr Lavrov told reporters at the Russian embassy after meeting Mr Trump. The meeting was the highest-level encounter between the United States administration and Moscow since Trump's inauguration. During that trip, Tillerson said relations with Russian Federation were at a low and needed to be rebuilt. "So we'll look at the proposal and see if it can work".
At another point, he mocked the idea, saying it must be "humiliating for the American people to realize the Russian Federation is controlling the situation in the United States".
In contrast, he credited Trump and Secretary of State Rex Tillerson, whom he met earlier in the day, with taking a "businesslike" approach that is "free from ideology", focused on reaching agreements.
US President Donald Trump is seeking "mutually beneficial" and "pragmatic" relations with Moscow, Russian Foreign Minister Sergei Lavrov said on Wednesday after White House talks with the Republican leader. "You are kidding. You are kidding".
The Kremlin press service reported earlier that during the May 2 telephone conversation, Putin and Trump had discussed a number of pressing issues related to bilateral cooperation, including the prospects for coordinating steps in the fight against terrorism in Syria and solving the North Korea issue.
It also will be a sign that the two countries have improved ties.
The meeting between the two men was expected to be "broad, blunt and businesslike", a senior official told CNN ahead of the meeting.More news: Bhagwant Mann appointed as AAP's state convener in Punjab

During the meeting, Trump also raised Ukraine, and expressed his administrations commitment to remain engaged in resolving the conflict and stressed Russias responsibility to fully implement the Minsk agreements.
But Mr Lavrov said he detected a US willingness to participate, especially with a zone being formed in Syria's south, near the border with Israel and Jordan.
Asked by a reporter if Comey's dismissal would cast a shadow over his talks with Tillerson, Lavrov acknowledged the elephant in the room by replying in a sarcastic tone: "Was he fired?"
The announcement came as Trump's campaign was being investigated by USA authorities for possible connections with Russian Federation. "It's standard practice", the official said.
White House spokesman Sarah Huckabee Sanders said Mr Trump had considered firing Mr Comey "since the day he was elected president".
Trump asked Russian Federation to rein in the authoritarian Assad regime of Syria, Iran and Iranian proxies.
Lavrov said Trump was seeking "mutually beneficial" and "pragmatic" relations with Russian Federation.
The US missile strike angered Moscow and led Lavrov to declare that "it's sad how damaging this is to the already bad relations between US and Russian Federation".
The two leaders held discussions at the Oval Office on a host of issues and the USA president described his meeting with Lavrov as "very, very good". As NPR's Domenico Montanaro reports, the firing of Comey with more than six years left on his term in office has prompted a flurry of questions about the president's motives - and about what's next.
