Prime Minister Narendra Modi was given a warm welcome by Bharatiya Janata Party workers and supporters on Thursday as he returned from the three-nation tour.
"All the leaders I met and all the personalities I spoke to have been so mesmerised and appreciative of India holding the G20 presidency so excellently. This is a matter of great pride for all Indians," Modi said.
The prime minister had visited Japan's Hiroshima to attend the Group of Seven or G7 Summit.
He then travelled to Papua New Guinea, which was his first tour, as well as the first-ever visit by any Indian prime minister to the Indo-Pacific country.
Modi also travelled to Sydney at the invitation of Australian Prime Minister Anthony Albanese.
He said that he used every available time in the best possible way for the good of the country.
Taking a swipe at critics, he said they questioned the decision to give away vaccines to other countries during the COVID-19 pandemic.
"Remember, it is the land of Buddha, it is the land of Gandhi. We care even for our enemies, we are the people inspired by compassion," the prime minister underlined.
He also asserted that the world is keen to listen to India's story and said Indians should never suffer from "slave mentality" while speaking about their great culture and traditions and instead speak with courage.
Modi added that the world agrees with him when he says any attack on the country's pilgrimage site is not acceptable.
