That's quite a common time (10-13 minutes) from cruising altitude to landing at most airports in East Asia. America has other issues that interfere with more sensible landing procedures that need to be addressed, but are unlike to be.
An extra ten or twenty seconds between planes taking off and landing can have a large impact over the course of a day. In the US the majority of flight delays are in the late-afternoon and into the evening because of the knock-on effect of delays (at that airport or others) and the lack of spare capacity within the timings to adjust the scheduling of takeoffs and landings.
