Ahead of his second round of informal talks with Chinese President Xi Jinping today, Prime Minister Narendra Modi went plogging on a beach in Mamallapuram, about 50 km from Chennai, in a 30-minute cleanliness drive this morning as he urged the people across the country to "ensure our public places are clean and tidy". In a video tweeted by PM Modi, he is seen picking up litter at a beach near Taj Fisherman's Cove Resort and Spa where he is staying."Plogging at a beach in Mamallapuram this morning. It lasted for over 30 minutes. Also handed over my 'collection' to Jeyaraj, who is a part of the hotel staff," he tweeted.
