Know why PM Modi's chemistry with Chinese President Xi Jinping is not as good as other world leaders?

Donning the traditional Tamil attire of 'veshti' (white dhoti), half-sleeve white shirt and angavastram over his shoulder, Modi welcomed Xi at Mamallapuram, also known Mahabalipuram, for the second informal India-China Summit.
Xi, who arrived earlier from Beijing, was equally casually attired in a white shirt and black trousers.
Modi received Xi near Arjuna's Penance and took him inside the rock-cut temple and was seen explaining the features to the Chinese leader.
Then the two leaders walked over to Arjuna's Penance sculpture. Modi, like a professional guide, was seen explaining to Xi the various images carved on the huge rock.
