India celebrates the Republic Day on January 26 to honor the adoption of the Consitution of India 73 years ago.
"We set a high value on the relations of privileged strategic partnership between our states. I am confident that by working together we can ensure the continued growth of mutually beneficial bilateral cooperation in all areas. This undoubtedly meets the fundamental interests of the friendly peoples of Russia and India," Putin said in a congratulatory telegram, published by the Kremlin.
The Russian president also outlined India's achievements reached in economic, social, research and technology and other areas, saying that India is making "substantial contribution" to ensuring international stability and security as well as addressing "vital" regional and international issues.
Republic Day is celebrated in India since January 26, 1950, when the country's constitution entered into force. The first years of celebrations were conducted at various sites in New Delhi. Since 1955 a parade along the main capital's avenue of Rajpath takes place annually.
