"if you are far from an enemy, make them believe you are near them." what is the meaning of this quote? and what's it's significance?

It's like they say, keep your friends close and your enemies closer. If someone is your friend you usually trust them and know that they won't do anything wronging against you. If they are your enemy then you probably won't trust them. They might find ways to "hurt" you in a sense. It is significant because it is a smart strategy. If you have your enemies close the you will get to know them better and know their way of acting and their tactics before they can do any wrong against you. Hope this helps.
