The goal of a country with a healthy economy is to have a balance of payments equal to zero.
The balance of payments is a record of all transactions between a country and the rest of the world. It includes the trade balance (exports minus imports), as well as other transactions such as foreign aid, investment, and tourism.
A balance of payments equal to zero means that a country is neither a net borrower nor a net lender to the rest of the world. This is generally seen as a sign of a healthy economy, as it indicates that a country is able to pay for its imports with its exports, and is not relying on borrowing or aid to finance its activities.
