Answer:
Balance of trade; trade surplus.
Step-by-step explanation:
When there exists a difference between export and import, it is called the balance of trade. As the country of East Anglia exports products and imports products domestically, and there is a comparison between the country's imports and exports, it results in the balance of trade.
When a country's export is more than its imports, it refers to a trade surplus. According to the question, the country has more export than imports.
