點解Foreign price 跌,exports都跟住跌?

If the foreign ( Imported ) price is down, the product, A, is much cheaper for users. So, if we are also selling this product A to foreign users, we will face a fiece competition as our price is relatively higher than the price before. In theory, the foreign users will buy the product A from other suppliers and not from us anymore. Hence, our export will then be reduced.
