How would a receding sea level affect cities along Asian & Australian coastlines?

To make a long story short, the previous ice age resulted in not just massive glaciers and building snow from appearing, but larger landmass as well due to most of the water being frozen from the colder climate. If a similar (if not worse) ice age were to occur a few thousand years in the future (assuming today's larger cities and cultural hubs still exist), how would this affect Asian and Australian coastlines?

To be more specific: how would the CITIES along these coasts be affected over years of lowering sea level?

If you need a reference, take a look at this map, which is similar to my proposed setting:
