An air curtain is actually a stream of air directed across a doorway, usually to prevent drafts or something of the sort.
But in our discussion today, we use the term air curtain as an economic figure of speech.

Netherlands, England, and other European governments are taking extreme measures to maintain their top spot in the world market.
Asian countries are also fighting to reach the top.
