The overriding theme in Modi's speech was to modernize India's ports and integrate them with special economic zones, port-based smart cities, industrial parks, warehouses, logistics parks and transport corridors.
Seeking partnership, Modi made a specific reference to rating agency Moody's recent appreciation of the Make in India initiative.
"We have done a lot of corrections on the front of ease of doing business. We have jumped 12 ranks in the World Bank’s ranking," the Prime Minister said, adding India has liberalised the licensing regime, including that of defence and ship-building sectors.
Backing up his assertions, he said FDI inflows have gone up by 44 per cent since his government took over.
"In fact, 2015-16 has seen the highest ever FDI inflow into India," Modi noted.
In 2015, India saw the highest-ever volume of cargo handled by its major ports. Port efficiency parameters have improved and India notched up fastest average turnaround time in ports in the same year, he added.
"In the last two years, our major ports have added 165 million tonnes of capacity with record addition each year. 94 million tonne capacity was added by these ports in 2015-16 alone, which is the highest ever," he said.
The Prime Minister said the shipping ministry is showcasing about 250 projects with investment opportunity in the maritime sector. These projects include infrastructure development opportunities in 12 major Ports, projects in eight maritime states and other agencies.
The initiatives would create employment opportunities of approximately 10 million jobs over the next 10 years, which includes 4 million direct and 6 million indirect jobs, he added.
Modi also touched upon more than 14,000 kilometers of navigable inland waterways in the country with tremendous potential.
Speaking at the same event, Union Shipping and Ports Minister Nitin Gadkari said: We've launched Project Unnati for major ports and already, there has been a 30 per cent increase in efficiency... We plan to double the port capacity in the next 10 years, which will include building 6-8 major ports at an investment of Rs 50,000 crore."
Plans are also afoot for developing 40 coastal SEZs which would create 1 lakh jobs.
Kim Young Suk, Minister of Oceans and Fisheries, South Korea, called for tapping similarities of both India and South Korea.
"India is well endowed with growth through oceans and South Korea is well positioned to offer its technology and expertise to support India," Kim added.
Governor of Maharashtra K Vidyasagar Rao, Chief Minister Devendra Fadnavis, Gujarat Chief Minister Anandiben Patel and Secretary General of IMO, Kitack lim, were present.
The traffic in major ports has shown a healthy growth of more than 4 per cent in the last two years, despite global slowdown.
The Prime Minister said major ports have awarded 56 new projects entailing an investment of more than Rs 250 billion, which will create an additional port capacity of 317 million tonnes per annum, and the vision is to increase port capacity from 1,400 million tonnes to 3,000 million tonnes by 2025.
"However, this is just the beginning. We want to do more. We are enhancing our own capacities of execution and implementation," Modi said.
To broaden livelihood opportunities further, the government is planning to deploy modern and sophisticated fishing vessels, which would enable them to harness resources in India's exclusive economic zone.
It is also focusing on value addition in fisheries, aquaculture and cold chain development.
During his speech, the Prime Minister raised the issue of climate change.
"The challenges of climate change have shown that even offshore human behaviour can change the ecology of glaciers and oceans. This is already causing a lot of concern for island countries and coastal communities in particular. I hope this summit will deliberate on these issues," he added.
Highlighting how joint efforts by nations can yield results, he spoke about elimination of sea piracy, which was seen as a big threat to international shipping a few years ago.
Invoking B R Ambedkar, Modi said it's a conscious decision to hold this important Summit on his birth anniversary.
"Today is the 125th birth anniversary of a great son of India who also lived and worked in Mumbai. I am referring to Dr B R Ambedkar, who was the architect of our Constitution. He is also the architect of the water and river navigation policy in India," Modi explained.
"Many of us may not know that Babasaheb created two powerful institutions related to water, navigation and power. They are the Central Waterways, Irrigation and Navigation Commission and the Central Technical Power Board."
