This is an example of what I call a “mystery scam” — an approach that is becoming more popular among email scammers. (See more examples of mystery scams.) They try to hook you into replying with a very brief message, promising a mysterious benefit:
From: Akhmed Dubayev firstname.lastname@example.org
Date: Fri, 15 Jun 2015
I seek your consent for an urgent business deal for you
Chan Wei Sang
But why would someone named “Chan Wei Sang” be sending messages from the address of “Akhmed Dubayev” in Denmark? (That’s what the .dk address means.) The answer is that these email addresses are all phony or are hacked, and there really is no business deal — just a fraudster trying to separate you from your money.
