Yes what you have heard is completely true. Modi on his arrival to Russia received a grand welcome in Moscow.
After his landing, the Russian band started playing India’s National Anthem ‘Jana Gana Mana’.
As a salute and respect every Indian will stand up and resume their work when National Anthem is playing.
But, Modi who represents India made a mistake when National Anthem is playing by Russian troop.
As soon as Jana Gana Mana started playing, Modi started to walk forward. Identified by a Russian official rushed towards Modi and stopped him from walking as it is a disrespect to Indian Anthem.
Realizing his mistake, Modi then stood in attention and as the band completed he started to move.
