"Good Luck Vishy! Conveying my best wishes to our pride, Viswanathan Anand for the World Chess Championship in Sochi," Modi tweeted.
The much-awaited clash will conclude on November 28 during which Anand will take on Carlsen in a repeat of the 2013 World Championships.
The Indian had been outwitted on his home turf of Chennai by Carlsen the last time around. Anand earned a shot at the title by winning Candidate's Tournament earlier this year.
