Canadian Prime Minister Justin Trudeau's India trip that began on Saturday has been making the headlines in India for the wrong reasons.

In the past four days of his first India trip as prime minister, Trudeau has travelled to the iconic Taj Mahal, nearly 200km from the capital, New Delhi and Gujarat, home state of Prime Minister Narendra Modi, and Mumbai, but no senior government minister has met him so far.

A junior Indian minister greeted the Canadian prime minister when he landed in New Delhi accompanied by his wife and three children.

Modi has broken protocols in the past to receive guests personally, including Israeli Prime Minister Benjamin Netanyahu in January.

But the Indian prime minister, who famously hugs his guests, has not even tweeted welcoming Trudeau in a move being seen as a "snub" to the Canadian leader.

The right-wing ruling Bharatiya Janata Party (BJP), however, denies any disrespect to the visiting leader.

Modi is scheduled to meet Trudeau on Friday.
