Prime Minister Narendra Modi and Russian President Vladimir Putin's latest shared car ride has become a striking symbol of the warmth between the two leaders. Their fourth joint car journey, after rides in Tianjin, New Delhi and Bishkek, came after an hour-long bilateral covering defence, energy, security and the Russia-Ukraine conflict. With both leaders appearing relaxed and comfortable, the short ride offered another glimpse into a relationship where personal chemistry has become part of the diplomatic message.
