In order for a country to import any good, the world price of that good must be lower than its domestic price. If the world price is higher, then there is no reason why anyone would import a good just to pay a higher price. E.g. the world price of corn is $10 per bushel, and the domestic price of corn is $12 per bushel. At these price levels, the country will import corn until the domestic and world price are equal. But if the domestic price is $10 and the world price is $12, then the country will export corn until both prices are equal.
