SEA GATE to SEA GATE
RHINE DANUBE CANAL IS WATER CONNECTION NORTH SEA TO AEGEAN SEA WITH THE 2 COUNTRIES AS GATES TO EACH

Solution

Map shows the connection of the two countries as gates to their adjacent seas as well as their reltive closeness in spite of being on two different continents — as gates they control the commerce of central Europe with the rest of the World. They are also relatively the same size and both historically doinated a large area of their neighbors. It is not surprising that their interests   coincide and this map celebrates that.
