Does a vehicle entering an intersection marked in such a way have priority over a vehicle moving around the central Island?

Why?

The entrance is marked with an A-7 give way sign and a C-12 roundabout sign. Together, these signs give priority to vehicles already on the roundabout, so entering drivers must give way.
