Indian Prime Minister Narendra Modi picked up rubbish on Saturday from a scenic beach resort where he was hosting Chinese President Xi Jinping for summit talks.

Mr Modi and Mr Xi were meeting in the southern town of Mamallapuram, home to old wind-swept temple monuments but also popular with tourists for surfing in its perfect waves.

But the prime minister released a video of himself going "plogging" – an activity where joggers combine their run or walk with picking up the rubbish - on the beach outside his luxury resort.

He collected plastic bottles - on which he has declared war - as well as banana skins and other litter in a big plastic bag, in his latest effort to highlight the lack of cleanliness in public places in India.

"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.

"Let us ensure our public places are clean and tidy! Let us also ensure we remain fit and healthy."

Indian cities have some of the world's highest levels of atmospheric pollution but they are also among the dirtiest with piles of rubbish lying in big centres like Delhi and Mumbai because of rapid urban growth and poor governance.

Mr Modi has called for an end to the consumption of single-use plastics by 2022.

Concerns are growing worldwide about plastic pollution, especially in oceans, where nearly 50% of single-use plastic products end up, killing marine life and entering the human food chain, studies have shown.

The Indian Prime Minister gave a personal tour to Mr Xi of the Shore Temple, dating back to the seventh and eighth century and other ancient monuments that are part of UNESCO's world heritage sites and which were emptied of all visitors for the two-day summit.
