This drop is primarily due to the imposition of the capital controls and may therefore be reversed once the controls are fully removed.
In 2016 in particular, as a result of the capital controls and low freight rates, receipts from sea transport services accounted for a mere 23% of total receipts in the services balance and financed 35% of the goods deficit, while net receipts (receipts less payments) accounted for 29% of the surplus of the services balance.
