NEW DELHI: Prime Minister Narendra Modi asserted on Sunday that the India-Middle East-Europe corridor will become a basis of world trade for the coming centuries and history will remember that it was envisioned in India.

In his monthly Mann ki Baat broadcast, Modi recalled the "Silk Route", an ancient trade corridor used by India when it was a prosperous and great trading power, and said the country suggested the India-Middle East-Europe economic corridor at the recent G20 Summit.

The successful summit after the success of India's Chandrayaan-3 mission doubled every citizen's happiness, he said while noting that the two accomplishments have figured most in the messages he has received from people.

India's leadership was acknowledged by the world as it succeeded in making the African Union a member of the G20, he said.

Bharat Mandapam, the venue that hosted the G20 Summit, has become a "celebrity", the prime minister said, noting that people have been clicking selfies with the state-of-the-art conference hall.

Noting that World Tourism Day falls on September 27, he said tourism is said to create maximum employment with minimum investment, adding that goodwill matters a lot in drawing tourists.

India's goodwill has risen over the last few years, he said, adding that it has only gone up further with the G20 meetings as over one lakh foreign delegates travelled to different parts of the country and witnessed its diversity and heritage.

Modi said it was a matter of immense pride that Santiniketan associated with Gurudev Rabindranath Tagore and the Hoysala temples of Karnataka were recently declared world heritage sites.

Such sites number 42 in India and it is the country's efforts to have more and more places associated with its culture and heritage recognised as the World Heritage Sites.

With Mahatma Gandhi's birth anniversary falling on October 2, he said no one can forget the sight of world leaders paying homage at his memorial during the G20 Summit, a recognition of how his ideas remain relevant globally.

Modi expressed happiness at many cleanliness programmes being planned to mark his birth anniversary with the Union government departments launching the 'Swachhta hi sewa' programme.

Noting that a big cleanliness programme will be organised at 10 am on October 1, he urged people to join the exercise in their neighbourhood or any public place.

It will be a true tribute to Gandhi ji, he said and asked people to buy some khadi products.

With the festival season coming up, he asked people to remember 'vocal for local' and buy 'Made in India' products.
