Days after being mocked by the Congress over his hugs, Modi said in a TV interview had he been "trained", he too would have followed the laid down protocols of shaking hands and "looking left and right" with world leaders.
"I do not know all the protocols as I am a common man. The openness of this common man is liked by the world. Friendly relations come in handy," he said in the interview to Zee news.
