Ms Swaraj is visiting Russia at the invitation of Deputy Prime Minister and Presidential Plenipotentiary Envoy to the Far Eastern Federal District Yury Trutnev.
"The External Affairs Minister's visit reflects the importance attached by India to emerging opportunities in the Russian Far East, and to its strategic partnership with Russia," the External Affairs Ministry had said last week.
The Eastern Economic Forum is considered as the biggest international communication platform for cooperation between businesses leaders and senior government representatives from Russia, the Pacific Region and the Association of Southeast Asian Nations (ASEAN).
Ms Swaraj's trip to Russia follows the visit of Prime Minister Narendra Modi as guest of honour at the St Petersburg International Economic Forum in June.
