According to the ministry, Soini is also expected to meet in Moscow with representatives of local civil society organizations.
Russian Foreign Ministry spokeswoman Maria Zakharova said earlier that Soini would arrive in Moscow on the invitation of Lavrov and it would be the first Soini's visit to Russia since he took office in May 2015.
In an interview with Sputnik, published on Saturday, Zakharova stressed that Russia and Finland managed to retain constructive relations despite the negative political backdrop of the Russia-EU ties.
Zakharova reminded that Moscow and Helsinki worked together in the United Nations, international organizations and regional formats in Northern Europe and the Arctic while Lavrov and Soini in 2015 met on the sidelines of international conferences three times — in New York, in Finland's city of Oulu and in Belgrade.
