Nauru has asked Japan to help rebuild the island's main quay.
The President Sprent Dabwido says an upgrade of the quay wall would be highly positive for Nauru.
He says it would speed up unloading and loading shipping containers and allow foreign fishing vessels to dock for refuelling and to replenish supplies.
It is the second time Nauru has presented a case on the quay wall proposal, which Japan estimates will cost more than 20 million US dollars.
Meanwhile, Nauru is considering changing the way it sells its phosphate.
Instead of individual contracts it will invite interested buyers to submit proposals for purchasing phosphate.
But the President says to safeguard Nauru's interests, buyers may be asked to make a deposit before placing a bid.
