Addressing the Institute of South Asian Studies' International Conference on South Asia, the Minister said the countries in the two regions should maximise opportunities to increase connectivity via air, land, sea and digital technology.
"Currently, 90 per cent of trade between South Asia and South east Asia are by sea," he said, urging the regions to fully maximise the opportunities of maritime connectivity.
"So, there is still much hope for investment in port infrastructure. It will take time but make sure we fully exploit the sea between us," said Balakrishnan, calling for investments in related infrastructure.

"There are so many existing airports, that can and should be upgraded," he said, adding that airlines were available.
He, however, pointed out protectionism of national airlines.

"The future is bright for both South Asia and South East Asia but there is some homework that we need to do," said Balakrishnan, stressing the need for good sense and good willto achieve it.
