Answer:
Net export or Balance of trade
Step-by-step explanation:
The difference in exports and import for n entity or a country is known as the balance of trade or net exports.
As such where Romernia, an Asian country, imported goods and services worth $700 million in the last fiscal year and exported goods worth $400 million in the same year.
Romernia's net export of balance of trade is ($300 million). Negative because the export is less than the import.
