Recommended replication strategy for fast global access to MySQL DB

The app i'm working on has users from all over the world and due to the nature of the app, i need to minimize all delays. My application servers are located in different data centers across the world and load balancing is in place. The load of the DB isn't that high, so that's not an issue, the issue is simply that i need to minimize delays across long distances somehow. Currently, there's a single DB server and it's located in Europe and the issue is when my app server in South-East Asia requests data from the DB in Europe, the complete duration for the query easily increases tenfold (from 50ms to 500ms). My initial idea is to add another DB server in Asia, what kind of replication should i set in that case? Or is this even a good way to go? Any guidelines and suggestions for this scenario are welcome.
